Description

Device memory management method and device, terminal device and storage medium

Technical Field

The present application belongs to the field of terminal technologies, and in particular, to a device memory management method and apparatus, a terminal device, and a computer-readable storage medium.

Background

With the intelligent development of terminal equipment, more and more applications are installed in the terminal equipment, so that more and more files are stored in the terminal equipment. Due to the limited memory resources of the terminal equipment, when a large number of files are stored in the terminal equipment, the terminal equipment has insufficient memory, and the normal use of the terminal equipment is affected. When the memory of the terminal device is insufficient, in the prior art, a user needs to manually select a backup file, backup the selected backup file to a storage device such as a cloud, and then manually clean the backup file to release the memory resource of the terminal device, so that the operation process is complicated, and the memory cleaning efficiency is low.

Disclosure of Invention

The embodiment of the application provides a device memory management method and device, a terminal device and a computer readable storage medium, which can simply and efficiently manage a device memory and improve user experience.

In a first aspect, an embodiment of the present application provides a device memory management method, which is applied to a first terminal device, and the method may include:

detecting a used memory of the first terminal device;

when the used memory is larger than or equal to a preset threshold value, determining a file to be transferred and stored in the first terminal device, and determining a second terminal device for receiving the file to be transferred and stored;

and sending the file to be transferred to the second terminal equipment, and deleting the file to be transferred in the first terminal equipment.

It should be understood that the first terminal device may detect the used memory of the first terminal device when the user is using the first terminal device, or may detect the used memory of the first terminal device when the first terminal device is idle, which is not limited in the embodiment of the present application. The step of detecting the used memory of the first terminal device means detecting the memory size of the used memory in the first terminal device.

For example, to reduce the detection power consumption of the first terminal device and prolong the usage time of the first terminal device, a detection period may be set to periodically detect the used memory of the first terminal device. The detection period may be set by the user, or may be set by default by the first terminal device.

It should be noted that the preset threshold may be preset according to the total memory of the first terminal device. When the used memory of the first terminal device reaches a preset threshold, it can be determined that the first terminal device is currently in a state of insufficient memory, and a function of intelligent transfer of the first terminal device needs to be started to transfer a file to release the memory resource of the first terminal device. The intelligent unloading function of the first terminal device can be started manually by a user or automatically by the first terminal device. Illustratively, the user may manually start the intelligent unloading function when the first terminal device detects that the memory is insufficient, or may start the intelligent unloading function in advance, that is, the intelligent unloading function may be started at any time when the memory of the first terminal device is sufficient, so that the first terminal device may directly perform file unloading to release the memory resource of the first terminal device when the memory of the first terminal device is insufficient.

Illustratively, the method may further comprise:

and generating a preview file corresponding to the file to be transferred and stored, and storing the preview file in the first terminal device, wherein the occupied memory of the preview file is smaller than that of the file to be transferred and stored.

It should be noted that, when the file to be transferred needs to be transferred, the first terminal device may further generate a preview file corresponding to the file to be transferred and store the preview file in the first terminal device, so that a user may view the file to be transferred in the first terminal device when needed. The occupied memory of the preview file is far smaller than that of the file to be transferred, so that the generated preview file does not obviously influence the available memory of the first terminal equipment.

In a possible implementation manner of the first aspect, the determining the file to be transferred in the first terminal device may include:

and acquiring the use frequency of each file in the first terminal equipment, and determining the file to be transferred and stored in the first terminal equipment according to the use frequency, wherein the file to be transferred and stored is at least one of the files.

In another possible implementation manner of the first aspect, the determining the file to be transferred in the first terminal device may include:

acquiring the occupied memory of each file in the first terminal device, and determining the file to be transferred and stored in the first terminal device according to the occupied memory of each file, wherein the file to be transferred and stored is at least one of the files.

The files to be transferred and stored, which can be transferred and stored, can be determined according to the use frequency of each file, so that the files used at low frequency in the first terminal device are transferred and stored, and the influence on the use of the first terminal device by the user is reduced. In addition, the file to be transferred and saved, which can be transferred and saved, can be determined according to the memory occupied by each file, for example, the file with a large memory occupied can be determined as the file to be transferred and saved, so as to effectively increase the available memory of the first terminal device. Of course, the file that can be transferred can also be determined by comprehensively considering the use frequency of the file and the occupied memory.

In a possible implementation manner of the first aspect, the determining the second terminal device that receives the file to be transferred may include:

determining the file type of the file to be transferred and the device type of each third terminal device, and determining a second terminal device for receiving the file to be transferred according to the file type and the device type, wherein the second terminal device is at least one terminal device in the third terminal devices, and the third terminal device is a terminal device in communication connection with the first terminal device.

In another possible implementation manner of the first aspect, the determining the second terminal device that receives the file to be transferred may include:

and obtaining the current residual memory of each third terminal device, and determining a second terminal device for receiving the file to be transferred according to the current residual memory of each third terminal device, wherein the second terminal device is at least one terminal device in the third terminal devices, and the third terminal device is a terminal device in communication connection with the first terminal device.

It should be noted that, in this embodiment of the present application, a target terminal device to which a file is preferentially transferred may also be set in advance, and when the file is required to be transferred, the file to be transferred may be preferentially transferred to the target terminal device. For example, the storage device such as the cloud or the hard disk, which only stores the file, may be set as the target terminal device for the preferential file transfer, so that the file to be transferred may be preferentially transferred to the storage device such as the cloud or the hard disk when the file is transferred. When the space of the storage devices such as the cloud/hard disk is insufficient, the second terminal device receiving the file to be transferred can be determined to transfer the file to be transferred according to the corresponding relationship between the file type and the device type and/or according to the current remaining memory of each third terminal device, and at this time, the determined second terminal device does not include the storage devices such as the cloud/hard disk.

In the embodiment of the present application, a target terminal device for preferentially unloading a file may also be set in advance for a file of a specified type. For example, the target terminal device that can set priority for transferring files frequently used by users, such as pictures, audio, video, and documents, is a storage device, such as a cloud/hard disk, so that when a certain file to be transferred is a picture, audio, video, or document, the file to be transferred can be preferentially transferred to the storage device, such as the cloud/hard disk. When the space of the storage devices such as the cloud/hard disk is insufficient, the second terminal device receiving the file to be transferred can be determined to transfer the file to be transferred according to the corresponding relationship between the file type and the device type and/or according to the current remaining memory of each third terminal device, and at this time, the determined second terminal device does not include the storage devices such as the cloud/hard disk.

Illustratively, after deleting the file to be transferred in the first terminal device, the method may include:

and when the instruction for acquiring the file to be transferred is detected, indicating the second terminal equipment to send the file to be transferred to the first terminal equipment.

Here, the user can download the file to be transferred to the second terminal device back to the first terminal device as needed in real time. When the distance between the first terminal device and the second terminal device is short, the first terminal device and the second terminal device can establish close-range communication connection, so that the file to be transferred is transmitted back to the first terminal device from the second terminal device through the distributed transmission capability of the near field. The Near Field Communication connection may be a bluetooth connection, a Near Field Communication (NFC) connection, a local area network connection, a Wireless-Fidelity (WiFi) connection, or a ZigBee (ZigBee) connection. When the distance between the first terminal device and the second terminal device is long, the first terminal device and the second terminal device can be connected through the internet, so that the file to be transferred and stored in the second terminal device in the first terminal device is downloaded back to the first terminal device through the network.

when an instruction for throwing the file to be transferred to a fourth terminal device is detected, determining whether the fourth terminal device is the second terminal device;

if the fourth terminal device is the second terminal device, indicating the second terminal device to present the file to be transferred and stored;

and if the fourth terminal equipment is not the second terminal equipment, indicating the second terminal equipment to deliver the file to be transferred to the fourth terminal equipment.

After the file to be transferred and saved is transferred and saved to the second terminal device, when a user needs to cast the file to be transferred and saved to the designated terminal device through the first terminal device for presentation, the first terminal device may not download the file to be transferred and saved back from the second terminal device, and then cast the file to be transferred and saved to the designated terminal device for presentation, but may directly instruct the second terminal device to perform presentation of the file to be transferred and saved, or may directly instruct the second terminal device to send the file to be transferred and saved to the designated terminal device for presentation, so as to improve the casting efficiency of the file to be transferred and saved, and improve the user experience.

when an instruction that the file to be transferred and stored is sent to a fourth terminal device is detected, sending the preview file corresponding to the file to be transferred and stored to the fourth terminal device, and indicating the second terminal device to send the file to be transferred and stored to a fifth terminal device corresponding to the fourth terminal device, or indicating the second terminal device to send the preview file corresponding to the file to be transferred and stored to the fourth terminal device, and sending the file to be transferred and stored to the fifth terminal device corresponding to the fourth terminal device.

Similarly, after the file to be transferred and stored is transferred and stored to the second terminal device, when the user needs to send the file to be transferred and stored to the designated terminal device, the first terminal device does not need to download the file to be transferred and stored back from the second terminal device, and then send the file to be transferred and stored, and can directly instruct the second terminal device to transmit the file to be transferred and stored, so that the sending efficiency of the file to be transferred and stored can be effectively improved, the memory consumption of the first terminal device can be reduced, and the user experience can be improved. In addition, in order to reduce the memory consumption of the specified terminal device, the preview file of the file to be transferred can be sent to the specified terminal device, and the original file of the file to be transferred can be sent to the terminal devices such as the cloud and the like corresponding to the specified terminal device.

In order to solve the above problem, embodiments of the present application provide a device memory management method, an apparatus, a terminal device, and a computer-readable storage medium, which can automatically screen a file to be transferred and saved in a first terminal device and automatically determine a second terminal device capable of receiving the file to be transferred and saved, then automatically transfer the file to be transferred and saved to the second terminal device, and automatically delete the file to be transferred and saved in the first terminal device to release a memory resource of the first terminal device, so that a user does not need to manually select, backup, delete, and the like the file to be transferred and saved, thereby simplifying a memory cleaning operation, improving memory management efficiency, and improving user experience.

Fig. 1 is a schematic structural diagram of a distributed storage system according to an embodiment of the present application. As shown in fig. 1, the distributed storage system may include a plurality of terminal apparatuses 101 that are communicatively connected to each other, where the plurality of terminal apparatuses 101 may be communicatively connected to each other through short-range communication or may be communicatively connected to each other through a network. Here, the first terminal device may be any terminal device in the distributed storage system, and the second terminal device may be a terminal device different from the first terminal device in the distributed storage system.

The memory between each terminal device in the distributed storage system can be commonly used. When the memory of the first terminal device is insufficient, the first terminal device can automatically transfer all or part of files in the first terminal device to the second terminal device, and release the memory resource of the first terminal device so as to ensure the normal use of the first terminal device. In other words, in the embodiment of the application, the plurality of terminal devices of the user form the distributed storage system, and the files in the terminal devices of the user are stored by using the distributed storage capacity, so that the reasonable allocation of the memory resources among the terminal devices of the user is realized, the memory utilization rate and the memory management efficiency of the terminal devices can be improved, and the user experience is improved.

It should be understood that the distributed storage system shown in fig. 1 includes 3 terminal devices for illustrative explanation only, and should not be construed as a limitation to the embodiment of the present application, and the number of terminal devices in the distributed storage system is not limited in the embodiment of the present application, and may be any number greater than or equal to 2.

In this application embodiment, the terminal device may be a mobile phone, a tablet computer, a desktop computer, a wearable device, a vehicle-mounted device, an intelligent television, an intelligent sound box, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), a cloud server, and the like, and the specific type of the terminal device is not limited in this application embodiment.

Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a device memory management method according to an embodiment of the present application, where the method may be applied to the distributed storage system, and an execution subject of the method may be a first terminal device in the distributed storage system. As shown in fig. 2, the method may include:

s201, detecting a used memory of the first terminal device.

It should be understood that the used memory refers to the memory occupied by various files such as pictures, audio, video, documents, compressed files, application programs, etc. in the terminal device. For example, the first terminal device may detect the used memory of the first terminal device when the user is using the first terminal device, or may detect the used memory of the first terminal device when the first terminal device is idle, which is not limited in the embodiment of the present application. The step of detecting the used memory of the first terminal device means detecting the memory size of the used memory in the first terminal device.

It should be noted that the first terminal device may detect the used memory of the first terminal device through a built-in memory detection application, that is, the memory detection application may count the memory occupied by each file in the first terminal device, so as to obtain the memory size of the used memory of the first terminal device.

Here, in order to reduce the detection power consumption of the first terminal device and prolong the service time of the first terminal device, in the embodiment of the present application, a detection period may be set to periodically detect the used memory of the first terminal device. The detection period may be set by the user, or may be set by default by the first terminal device. For example, the user may set the detection period to an arbitrary value such as 5 days, 10 days, 30 days, or the like by himself.

S202, when the used memory is larger than or equal to the preset threshold, determining a file to be transferred in the first terminal device, and determining a second terminal device for receiving the file to be transferred.

Here, the preset threshold is a preset numerical value used for determining whether the first terminal device is in a memory shortage state. For example, the preset threshold may be preset according to the total memory of the first terminal device. For example, the preset threshold may be set to any value such as 85% or 90% of the total memory of the first terminal device, that is, when the used memory of the first terminal device reaches 85% or 90%, it may be determined that the first terminal device is currently in a state of insufficient memory, and a function of intelligent transfer of the first terminal device needs to be started to perform file transfer to release the memory resource of the first terminal device. The intelligent unloading function of the first terminal device can be started manually by a user or automatically by the first terminal device. It should be understood that, when the first terminal device detects that the memory is insufficient, the user may manually start the function of the intelligent unloading, or may start the function of the intelligent unloading in advance, that is, the function of the intelligent unloading may be started at any time when the memory of the first terminal device is sufficient, so that when the first terminal device detects that the memory of the first terminal device is insufficient, the file unloading may be directly performed to release the memory resource of the first terminal device.

In one example, the first terminal device may display an icon and/or a menu bar of the smart load for a user to manually turn on a function of the smart load. For example, as shown in fig. 3 (a), the first terminal device may display an icon of the smart dump on a shortcut control interface, where the shortcut control interface may further include icons of conventional functions such as bluetooth, flight mode, movement data, wireless lan, flashlight, brightness, and the like, so as to implement shortcut operations of related functions such as bluetooth, flight mode, movement data, and the like. Alternatively, as shown in fig. 3 (b), the first terminal device may display the menu bar for the smart transfer in the setting interface, where the setting interface may further include a setting menu bar for conventional functions such as bluetooth, airplane mode, mobile data, and wireless lan, so as to implement setting operations for related functions such as bluetooth, airplane mode, and wireless lan.

It should be understood that when the first terminal device detects a relevant operation (such as a click operation or a touch operation) of the user on the shortcut control interface or the setting interface, the function of the intelligent unloading may be directly started, or the user may be asked through a popup window whether to determine to start the function of the intelligent unloading. For example, when the first terminal device detects that an icon of the smart dump is lit up as shown in (a) of fig. 3, or detects that an on-off key of a menu bar of the smart dump is turned on as shown in (b) of fig. 3, the first terminal device may directly turn on the function of the smart dump; or a popup window as shown in (c) of fig. 3 may be displayed to display "is it determined to turn on the smart dump? "and a" yes "or" no "selection key, when the first terminal device detects that the user clicks" yes ", the first terminal device may start the intelligent unloading function.

In an example, the first terminal device may also ask, through a popup window, whether the user starts the function of the intelligent unloading when detecting that the used memory of the first terminal device is greater than or equal to a preset threshold, or prompt the user to start the function of the intelligent unloading through the popup window. For example, when detecting that the used memory of the first terminal device is greater than or equal to the preset threshold, the first terminal device may display a popup window as shown in (a) of fig. 4 to display "is the memory insufficient, is the smart dump enabled? "and provide a selection key of" yes "or" no ", when the first terminal device detects that the user clicks" yes ", the first terminal device may start the function of intelligent unloading. Or, a popup window shown in fig. 4 (b) may be displayed to display "the memory is insufficient, please clean up in time", and provide a selection key for "ignore" and "set", when the first terminal device detects that the user clicks "set", the first terminal device may directly jump to the memory management interface, and the user may start the function of intelligent unloading in the memory management interface.

It should be understood that when the first terminal device detects that the user clicks "no" or "ignore", the first terminal device may perform the popup query or the popup prompt again after a preset time interval. Or, a plurality of different preset thresholds may be set in the first terminal device, when the first terminal device detects that the used memory of the first terminal device is greater than or equal to a first preset threshold (that is, a minimum preset threshold), the first terminal device may first inquire, through a popup window, whether the user starts the function of the intelligent transfer or first prompt, through the popup window, the user to start the function of the intelligent transfer, when the first terminal device detects that the user clicks "no" or "ignore", the first terminal device may perform popup inquiry or popup window prompt again when the used memory is greater than or equal to a second preset threshold (that is, a next smaller preset threshold), and so on.

For example, in an application scenario in which a preset threshold is set in the first terminal device as 85%, 90%, and 95% of the total memory of the first terminal device, when the first terminal device detects that the used memory of the first terminal device is greater than or equal to 85% of the total memory of the first terminal device, the first terminal device may first query, through the pop-up window, whether the user starts the function of the intelligent transfer, or first prompt, through the pop-up window, the user to start the function of the intelligent transfer, when the first terminal device detects that the user clicks "no" or "ignore", the first terminal device may perform the pop-up window query or pop-up window prompt again when the used memory is greater than or equal to 90% of the total memory of the first terminal device, and when the first terminal device detects that the user still clicks "no" or "ignore", the first terminal device may determine that the used memory is greater than or equal to 95% of the total memory of the first terminal device, and performing popup inquiry or popup reminding again.

It should be noted that, as shown in fig. 5 (a), the memory management interface may include user information, a total memory of all terminal devices associated with the user information (i.e., all terminal devices in the distributed storage system), a device management item, an intelligent transfer item, a setting item, a question and suggestion item, and the like. Here, when the user can click the smart transfer entry to enter the smart transfer interface as shown in (b) of fig. 5, a menu bar of the smart transfer may be displayed in the smart transfer interface, and the user may click the menu bar of the smart transfer to start the function of the smart transfer. After the function of the intelligent unloading is started, as shown in (c) of fig. 5, the storage device corresponding to each file may also be displayed in the intelligent unloading interface, where the user may also modify the storage device corresponding to each file in the intelligent unloading interface. For example, the device management item may display a total memory of all the terminal devices, a use condition of the total memory, each terminal device, the number of the terminal devices, and the like, and the user may further click the device management item to enter a device management detail page shown in (d) in fig. 5 to view a memory and a specific use condition of each terminal device, for example, view a used memory of each terminal device and a used memory of each type of file, and the like, where a first terminal device displayed in the device management detail page may be a terminal device (i.e., a first terminal device) currently operated by the user, and all the terminal devices may include a cloud of the user.

In an example, the first terminal device may also automatically start the function of the intelligent dump when detecting that the used memory of the first terminal device is greater than or equal to the preset threshold, without querying or prompting the user through a pop-up window.

It should be noted that, as shown in (a) of fig. 6, the popup query or the popup prompt may be displayed during the process that the user is using the first terminal device, or as shown in (b) of fig. 6, may also be displayed during the process that the first terminal device is turning on the screen, which is not specifically limited in this embodiment of the present application.

Here, when the used memory of the first terminal device is greater than or equal to the preset threshold and the intelligent unloading function of the first terminal device is started, the first terminal device may determine a file to be unloaded in the first terminal device and determine a second terminal device that may receive the file to be unloaded in the distributed storage system, so as to release the memory resource of the first terminal device by unloading the file to be unloaded by the second terminal device.

In one example, the first terminal device may determine the file to be dumped according to the frequency of use of the file. Specifically, the first terminal device may monitor the use state of each file in real time, so as to determine the use frequency of each file within the corresponding preset time according to the use state, and may determine N infrequent files with the lowest use frequency as files to be transferred, where N is an integer greater than or equal to 1; or, an uncommon file with a usage frequency lower than a preset frequency threshold value can be determined as a file to be dumped. The N, the preset time and the preset frequency threshold may be set by the user, or may be determined by the first terminal device through big data analysis of historical usage data of the user, which is not limited in the embodiment of the present application.

It should be noted that, in the embodiment of the present application, the same preset time may be set for different types of files, and different preset times may also be set for different types of files. In a specific application scenario, the preset time corresponding to all types of files may be uniformly set to 30 days, N may be set to 10 and/or the preset frequency threshold may be set to 3, that is, the first terminal device may count the usage frequencies corresponding to the files such as pictures, audio, video, documents, compressed files, application programs, and the like in the last 30 days, and may determine the 10 infrequent files with the lowest usage frequency as the files to be saved, or may determine the infrequent files with the usage frequency lower than 3 as the files to be saved.

In another specific application scenario, the preset time corresponding to the application program may be set to 90 days, the preset time corresponding to the picture may be set to 60 days, the preset time corresponding to the audio and the video may be set to 30 days, and the like, and N may be set to 5 and/or the preset frequency threshold may be set to 1, that is, the first terminal device may count the usage frequency of the application program in the last 90 days, the usage frequency of the picture in the last 60 days, the usage frequency of the audio and the video in the last 30 days, and the like, and may determine the 5 uncommon files with the lowest usage frequency as the files to be saved, or may determine the uncommon files with the usage frequency lower than 1 as the files to be saved. For example, when the first terminal device detects that a certain application program has not been used or upgraded in the last 90 days, the first terminal device may determine the application program as a file to be transferred; when the first terminal device detects that a certain picture is not viewed/edited in the last 60 days, the first terminal device can determine the picture as a file to be transferred; when the first terminal device detects that a certain audio/video is not opened in the last 30 days, the first terminal device can determine the audio/video as a file to be dumped, and the like.

In an example, the first terminal device may also determine the file to be transferred according to the occupied memory of the file. Specifically, in order to improve the release efficiency of the memory resources and effectively increase the available memory of the first terminal device, the first terminal device may determine N files occupying the largest memory as files to be transferred and stored, where N is an integer greater than or equal to 1; or determining the file occupying the memory larger than the first preset memory threshold value as the file to be transferred. It should be understood that, because files occupying a relatively large memory are often files frequently used by a user, in order to reduce the influence of memory release on the use of the first terminal device by the user, the first terminal device may also determine M files occupying the smallest memory as files to be transferred, where M is an integer greater than or equal to 1; or determining the file occupying the memory less than the second preset memory threshold value as the file to be transferred. The N, M, the first preset memory threshold and the second preset memory threshold may be set by the user, or may be set by the first terminal device by default according to an actual situation, which is not limited in this embodiment of the present application.

It should be noted that, the first terminal device may also determine the file to be transferred in consideration of the use frequency and the occupied memory of the file. For example, a file whose usage frequency is less than a preset frequency threshold and whose occupied memory is less than a second preset memory threshold may be determined as a file to be transferred; or the occupied memory is larger than a first preset memory threshold value, and the N files with the lowest use frequency are determined as the files to be transferred.

In a possible implementation manner, after determining the file to be transferred, the first terminal device may determine, according to the file type of the file to be transferred and the device type of each third terminal device, a second terminal device that receives the file to be transferred, where the third terminal device is a terminal device different from the first terminal device in the distributed storage system, and the second terminal device is at least one terminal device in the third terminal devices.

For example, the correspondence between the file type and the device type may be set in advance. After the first terminal device determines the file to be transferred, the file type of the file to be transferred can be obtained, and the second terminal device for receiving the file to be transferred can be determined according to the file type of the file to be transferred and the corresponding relation. For example, the terminal device for receiving image unloading may be a hard disk, the terminal device for receiving audio unloading may be a sound box, the terminal device for receiving video and document (including documents in various formats) may be a cloud, and so on. When the first terminal device determines that the file to be transferred is a picture, the second terminal device can be determined to be a hard disk; when the file to be transferred and stored is determined to be audio, the second terminal device can be determined to be a sound box; when the file to be transferred is determined to be a video or a document, it may be determined that the second terminal device is a cloud, and so on.

In another possible implementation manner, the first terminal device may obtain the current remaining memory of each third terminal device when determining the file to be transferred or after determining the file to be transferred, and may determine, according to the current remaining memory of each third terminal device, the second terminal device that receives the file to be transferred. For example, one or more third terminal devices with the largest current remaining memory may be determined as the second terminal device that receives the file to be transferred.

Here, in order to reduce the influence of the file dump on the functions of the second terminal device, such as file saving, and the like, a current available dump memory corresponding to each third terminal device may be determined according to the current remaining memory of each third terminal device, and one or more third terminal devices with the largest current available dump memory may be determined as the second terminal device that receives the file to be dumped. For example, 50% of the currently remaining memory of each third terminal device may be determined as the currently available dump memory corresponding to each third terminal device, so as to ensure that the second terminal device itself has enough memory to store/download the new file.

It should be noted that, in order to reduce the influence of file dump on functions of the second terminal device, such as file saving itself, in this embodiment of the application, the total memory of the terminal device that can be used to receive the file to be dumped may also be limited, for example, the total memory of the terminal device that can be used to receive the file to be dumped may be limited to the terminal device that is greater than or equal to 500GB, that is, when the first terminal device determines the second terminal device that receives the file to be dumped, only the third terminal device that has the total memory that is greater than or equal to 500GB is determined.

It should be understood that the first terminal device may also determine, by combining the correspondence between the file type and the device type and the current remaining memory of the third terminal device, the second terminal device that receives the file to be transferred. For example, the first terminal device may determine, according to the file type and the corresponding relationship of the file to be transferred, a second terminal device that receives the file to be transferred, and obtain a current remaining memory of the second terminal device, when the current remaining memory of the second terminal device is insufficient, the first terminal device may continue to obtain the current remaining memory of other third terminal devices (terminal devices other than the first terminal device and the second terminal device in the distributed storage system), and determine, according to the current remaining memory of the other third terminal devices, a terminal device that finally receives the file to be transferred. Here, when the first terminal device determines that the second terminal devices receiving the to-be-transferred file include a plurality of second terminal devices according to the file type and the corresponding relationship of the to-be-transferred file, the first terminal device may also determine the terminal device that finally receives the to-be-transferred file according to the current remaining memory of each of the second terminal devices.

In the embodiment of the application, a target terminal device for the preferential file transfer can be set in advance, and when the file transfer is required, the first terminal device can preferentially transfer the file to be transferred to the target terminal device. For example, the storage device such as the cloud/hard disk, which only stores the file, may be set as the target terminal device for the file to be preferentially transferred, so that when the file is transferred, the first terminal device may preferentially transfer the file to be transferred to the storage device such as the cloud/hard disk. When the space of the storage devices such as the cloud/hard disk is insufficient, the first terminal device may determine, according to the correspondence between the file types and the device types and/or according to the current remaining memory of each third terminal device, the second terminal device that receives the file to be transferred to perform the transfer of the file to be transferred, and at this time, the determined second terminal device may not include the storage devices such as the cloud/hard disk.

In the embodiment of the present application, a target terminal device for preferentially unloading a file may also be set in advance for a file of a specified type. For example, the target terminal device that is configured to preferentially dump files that are frequently used by users, such as pictures, audio, video, and documents, is a storage device such as a cloud/hard disk, so that when a certain file to be dumped is a picture, audio, video, or document, the first terminal device can preferentially dump the file to be dumped to the storage device such as the cloud/hard disk. When the space of the storage devices such as the cloud/hard disk is insufficient, the first terminal device may determine, according to the correspondence between the file types and the device types and/or according to the current remaining memory of each third terminal device, the second terminal device that receives the file to be transferred to perform the transfer of the file to be transferred, and at this time, the determined second terminal device may not include the storage devices such as the cloud/hard disk.

It should be noted that, the user may also manually set the second terminal device storing the file to be transferred. For example, the user may manually set a terminal device storing a file to be transferred through the pull-down menu 501 in the smart transfer interface as shown in (c) of fig. 5.

And S203, sending the file to be transferred to the second terminal equipment, and deleting the file to be transferred in the first terminal equipment.

It should be understood that, after determining the file to be transferred and receiving the second terminal device of the file to be transferred, the first terminal device may automatically move the file to be transferred to the second terminal device, and delete the file to be transferred in the first terminal device, so as to release the memory resource of the first terminal device. After the function of the intelligent dump of the first terminal device is started, in the process that the user subsequently uses the first terminal device, the first terminal device can directly and automatically determine the file to be dumped and the second terminal device at the background, automatically dump the file to be dumped to the second terminal device, automatically delete the file to be dumped in the first terminal device, and do not need to send a reminder of insufficient memory to the user, so that the user experience is improved.

For example, the first terminal device may retain a placeholder of the file to be transferred, that is, the user may still see the placeholder of the file to be transferred on the first terminal device, and may click the placeholder to see the preview file corresponding to the file to be transferred, so as to inform the user that the file to be transferred is not deleted but is not stored on the first terminal device through the placeholder.

In an example, after the to-be-transferred file is transferred to the second terminal device, the first terminal device may display an acquisition icon of the to-be-transferred file, for example, the acquisition icon of the to-be-transferred file may be displayed in a display interface of the preview file. When the user needs to perform related operations on the file to be transferred and saved in the first terminal device, the user may click or touch the obtaining icon to generate an instruction for obtaining the file to be transferred and the first terminal device may instruct the second terminal device to send the file to be transferred and saved back to the first terminal device based on the instruction. For example, after the first terminal device a uploads the document C to the second terminal device B, if the user wants to modify the document C in the first terminal device a, the user may click or touch the obtaining icon to generate an instruction for obtaining the document a, and after the first terminal device a detects the instruction, the second terminal device B may be instructed to send the document a back to the first terminal device a, that is, after the first terminal device a detects the instruction, the first terminal device a may send a file obtaining request to the second terminal device B to request to obtain the document C, and the second terminal device B may transmit the document C back to the first terminal device a based on the file obtaining request.

It should be understood that when the distance between the first terminal device and the second terminal device is short, a near field communication connection may be established between the first terminal device and the second terminal device, so as to transmit the file to be transferred from the second terminal device back to the first terminal device through the distributed transmission capability of the near field. The Near Field Communication connection may be a bluetooth connection, a Near Field Communication (NFC) connection, a local area network connection, a Wireless-Fidelity (WiFi) connection, or a ZigBee (ZigBee) connection.

When the distance between the first terminal device and the second terminal device is long, the first terminal device and the second terminal device can be connected through the internet, so that the file to be transferred and stored in the second terminal device in the first terminal device is downloaded back to the first terminal device through the network.

It should be noted that, after the file to be transferred and stored is transferred and stored to the second terminal device, the user may also perform related operations on the file to be transferred and stored on the first terminal device, such as an operation of delivering the file to be transferred and stored to the fourth terminal device through the first terminal device, an operation of sending the file to be transferred and stored to the fourth terminal device through the first terminal device, and so on.

In an example, when the first terminal device detects an instruction that a user requests to put a to-be-transferred file after being transferred to a fourth terminal device for presentation, the first terminal device may first determine whether the fourth terminal device is a second terminal device that stores the to-be-transferred file, and if the fourth terminal device is the second terminal device that stores the to-be-transferred file, may directly instruct the second terminal device to present the to-be-transferred file. If the fourth terminal device is not the second terminal device storing the file to be transferred, the second terminal device may be instructed to transfer the file to be transferred to the fourth terminal device, so that the fourth terminal device may directly present the file to be transferred after receiving the file to be transferred. Namely, when the user performs the relevant operation on the file to be transferred and stored to throw the file to be transferred and stored to the designated terminal device for presentation, the first terminal device does not need to download the file to be transferred and stored back from the second terminal device, and then throw the file to be transferred and stored to the designated terminal device for presentation, and can directly instruct the second terminal device to present the file to be transferred and stored, or can directly instruct the second terminal device to throw the file to be transferred and stored to the designated terminal device for presentation, so that the throwing efficiency of the file to be transferred and stored is improved, and the user experience is improved.

For example, after the first terminal device transfers the audio to the sound box, when the user wants to cast the transferred audio to the sound box for playing, the first terminal device may directly instruct the sound box to play the audio. For example, after the first terminal device transfers the video to the cloud, when the user wants to screen the transferred video on the television for display, the first terminal device may directly instruct the cloud to send the video to the television, and after the television receives the video, the video may be played. For example, after the first terminal device transfers the video to the cloud, when the user wants to screen the transferred video on a television for display and play the sound in the video through the sound box, the first terminal device may directly instruct the cloud to send the image data of the video to the television and send the audio data of the video to the sound box.

In an example, when the first terminal device detects an instruction that a user requests to send a to-be-transferred file after being transferred to a fourth terminal device, the first terminal device may directly instruct the second terminal device to send the to-be-transferred file to the fourth terminal device, where the fourth terminal device may be a terminal device in the distributed storage system that is different from the first terminal device and the second terminal device, or a terminal device outside the distributed storage system.

For example, after the first terminal device uploads the document C to the cloud a of the user a, when the user a wants to send the document C to the user B by using the first terminal device, the user a may send the preview file of the document C to the user B through a communication tool (e.g., an instant messaging application, a mailbox, etc.) in the first terminal device, and may select to send the preview file in an original sending mode, and the cloud a may send the document C to the fourth terminal device where the user B is located based on the original sending mode, so that the preview file of the document C is still found by the communication tool in the first terminal device of the user a, and the preview file of the document C is received by the fourth terminal device where the user B is located. That is to say, when the user a sends the saved document C to the user B by using the first terminal device, the user a may directly instruct the cloud a storing the document C to send the document C to the user B without downloading the document C to the first terminal device and then sending the document C, which may greatly improve the sending efficiency of the file and reduce the memory consumption of the first terminal device.

Or, the first terminal device may send the preview file corresponding to the to-be-transferred file to the fourth terminal device, and instruct the second terminal device to send the to-be-transferred file to the fifth terminal device corresponding to the fourth terminal device. Or the first terminal device may instruct the second terminal device to send the preview file corresponding to the to-be-transferred file to the fourth terminal device, and send the to-be-transferred file to the fifth terminal device corresponding to the fourth terminal device. The fifth terminal device may be a cloud terminal outside the distributed storage system, for example, the fifth terminal device may be a cloud terminal of the user B.

For example, after the first terminal device uploads the document C to the cloud a of the user a, when the user a wants to send the document C to the user B by using the first terminal device, the user a may send the preview file of the document C to the fourth terminal device where the user B is located through a communication tool (e.g., an instant messaging application, a mailbox, etc.) in the first terminal device, and at this time, the cloud a may also send the document C to a fifth terminal device (cloud) of the user B, so that memory consumption of the fourth terminal device is reduced on the basis that the user B can conveniently view the preview file of the document C in the fourth terminal device. When the user B wants to acquire the document C, the user B can acquire the document C through the cloud B. Here, the cloud a may also directly share the document C to the cloud B without sending the document C to the cloud B, that is, the document C may also be shared between the cloud a and the cloud B.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

As can be seen from the foregoing, the terminal device 8 may be a mobile phone, a tablet computer, a desktop computer, a wearable device, a vehicle-mounted device, an intelligent television, an intelligent sound box, a notebook computer, a UMPC, a netbook, a PDA, a cloud server, and the like. Take the terminal device 8 as a mobile phone as an example. Fig. 9 is a block diagram illustrating a partial structure of a mobile phone according to an embodiment of the present application. Referring to fig. 9, the handset may include: radio Frequency (RF) circuitry 910, memory 920, input unit 930, display unit 940, sensor 950, audio circuitry 960, wireless fidelity (WiFi) module 970, processor 980, and power supply 990. Those skilled in the art will appreciate that the handset configuration shown in fig. 9 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

The following describes each component of the mobile phone in detail with reference to fig. 9:

the RF circuit 910 may be used for receiving and transmitting signals during information transmission and reception or during a call, and in particular, for receiving downlink information of a base station and then processing the received downlink information to the processor 980; in addition, the data for designing uplink is transmitted to the base station. In general, RF circuit 910 may include, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, the RF circuit 910 may also communicate with networks and other devices via wireless communication. The wireless communication may use any communication standard or protocol, including but not limited to global system for mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE)), email, Short Message Service (SMS), and the like.

The memory 920 may be used to store software programs and modules, and the processor 980 may execute various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 920. The memory 920 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 920 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 930 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 930 may include a touch panel 931 and other input devices 932. The touch panel 931, also referred to as a touch screen, may collect a touch operation performed by a user on or near the touch panel 931 (e.g., a user's operation on or near the touch panel 931 using a finger, a stylus, or any other suitable object or accessory), and drive a corresponding connection device according to a preset program. Alternatively, the touch panel 931 may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 980, and can receive and execute commands sent by the processor 980. In addition, the touch panel 931 may be implemented by various types, such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 930 may include other input devices 932 in addition to the touch panel 931. In particular, other input devices 932 may include, but are not limited to, one or more of a physical keyboard, function keys (e.g., volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.

The display unit 940 may be used to display information input by the user or information provided to the user and various menus of the mobile phone. The display unit 940 may include a display panel 941, and optionally, the display panel 941 may be configured in the form of a Liquid Crystal Display (LCD), an organic light-emitting diode (OLED), or the like. Further, the touch panel 931 may cover the display panel 941, and when the touch panel 931 detects a touch operation on or near the touch panel 931, the touch panel transmits the touch operation to the processor 980 to determine the type of the touch event, and then the processor 980 provides a corresponding visual output on the display panel 941 according to the type of the touch event. Although in fig. 9, the touch panel 931 and the display panel 941 are two independent components to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 931 and the display panel 941 may be integrated to implement the input and output functions of the mobile phone.

The handset may also include at least one sensor 950, such as a light sensor, motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display panel 941 according to the brightness of ambient light, and a proximity sensor that turns off the display panel 941 and/or backlight when the mobile phone is moved to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile phone, further description is omitted here.

Audio circuitry 960, speaker 961, microphone 962 may provide an audio interface between a user and a cell phone. The audio circuit 960 may transmit the electrical signal converted from the received audio data to the speaker 961, and convert the electrical signal into a sound signal for output by the speaker 961; on the other hand, the microphone 962 converts the collected sound signal into an electrical signal, converts the electrical signal into audio data after being received by the audio circuit 960, and outputs the audio data to the processor 980 for processing, and then transmits the audio data to, for example, another mobile phone through the RF circuit 910, or outputs the audio data to the memory 920 for further processing.

WiFi belongs to short-distance wireless transmission technology, and the mobile phone can help a user to receive and send e-mails, browse webpages, access streaming media and the like through the WiFi module 970, and provides wireless broadband Internet access for the user. Although fig. 9 shows the WiFi module 970, it is understood that it does not belong to the essential constitution of the handset, and can be omitted entirely as needed within the scope not changing the essence of the invention.

The processor 980 is a control center of the mobile phone, connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 920 and calling data stored in the memory 920, thereby integrally monitoring the mobile phone. Alternatively, processor 980 may include one or more processing units; preferably, the processor 980 may integrate an application processor, which primarily handles operating systems, user interfaces, applications, etc., and a modem processor, which primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 980.

The handset also includes a power supply 990 (e.g., a battery) for supplying power to the various components, which may preferably be logically connected to the processor 980 via a power management system, thereby providing management of charging, discharging, and power consumption via the power management system.

The notification manager enables the application to display notification information in the status bar, can be used to convey notification-type messages, can disappear automatically after a short dwell, and does not require user interaction. Such as a notification manager used to inform download completion, message alerts, etc. The notification manager may also be a notification that appears in the form of a chart or scroll bar text at the top status bar of the system, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, prompting text information in the status bar, sounding a prompt tone, vibrating the electronic device, flashing an indicator light, etc.

The application framework layer may further include:

a viewing system that includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, the display interface including the short message notification icon may include a view for displaying text and a view for displaying pictures.

The telephone manager is used for providing the communication function of the mobile phone. Such as management of call status (including on, off, etc.).

The system layer may include a plurality of functional modules. For example: a sensor service module, a physical state identification module, a three-dimensional graphics processing library (such as OpenGL ES), and the like.

The sensor service module is used for monitoring sensor data uploaded by various sensors in a hardware layer and determining the physical state of the mobile phone;

the physical state recognition module is used for analyzing and recognizing user gestures, human faces and the like;

the three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.
