s102, after receiving the first request message, acquiring a target file required by the third equipment from the second equipment based on remote connection;

s103, sending the target file to third equipment;

and S104, after the target file is successfully sent to the third equipment, determining whether to delete the target file according to the network storage subscription information of the user account of the third equipment.

The second device and the third device may be both a smart phone, a tablet computer, a notebook computer, a personal computer, and the like, and the embodiment of the disclosure is not limited herein.

The first device may be a cloud platform or a server, or a network device capable of establishing a remote connection with the second device.

A remote connection is when a first device connects the second device remotely. Based on the remote connection, the first device may operate the second device in real-time.

The storage directory may include information such as a storage path of the file in the second device. The file identifier may include a file name of the file, for example, the file name may include a prefix name and a suffix name, the prefix name may be arbitrarily named, and the suffix name indicates a format type of the file. For example, the file is a word file, the suffix of the file name may be doc, and the file is a picture file, the suffix of the file name may be jpg or gif. The file icon includes an image identifier of the file, as shown in fig. 1B, and in some file icons, the file icon may be a dedicated icon representing the type of the file, such as a shortcut icon carried by a word file or a PDF file. While in other file icons, the file icon may be a user-defined icon.

The third device prestores a file icon generated according to the storage directory and the file identifier of the second device, that is, the third device is installed with an app of the second device, where the app may be an app capable of implementing file transmission and viewing functions stored in the second device, as shown in fig. 1B, and the app stores the file icon generated according to the storage directory and the file identifier of the second device.

When the third device monitors that the user acts on the file icon on the app, the file icon indicates that the user wants to view the file corresponding to the file icon, at this time, the third device sends a first request message to the first device, and after receiving the first request message, the first device can obtain a target file required by the third device from the second device based on remote connection, so that transmission and viewing of the target file can be achieved.

In the process, the second device serves as a storage device to store the file, the third device can establish remote connection with the second device through the first device, when the file stored in the second device needs to be read, the second device does not need to be found to check, only the first device needs to be sent with the first request message, and the problems that in the related art, the second device serves as the storage device to store the file, when a user needs to check the file stored in the second device, the second device needs to be found to check, and remote checking cannot be achieved are solved.

The second device may be an electronic device that is not used in a certain place (e.g., an electronic device that is not used at home by a user), and the third device may be an electronic device that is carried by the user.

Therefore, the user can still check the files stored in the second device in time under the condition that the user is out.

Meanwhile, the second device is used as a storage device to store the file, network disk resources can be saved, and compared with the prior art that a user needs to buy a commercial network disk to expand the capacity of the third device, the use of the commercial network disk by the user can be reduced, so that the cost can be reduced.

The first device may be a public network device or a non-public network device, and is not limited herein.

Whether the first device is a public network device or a non-public network device, the third device may have previously subscribed to the network to which the first device belongs, and the network to which the first device belongs may provide the network service for the third device according to the subscription information.

The subscription information may include network stored subscription information, subscription credentials, and the like.

The network storing the subscription information may include: the storage authority information of the user account, the capacity information of the storage space signed by the user, and the like.

In some embodiments, in the case that the first device is a non-public network device, the network storing the subscription information may further include: the network to which the user subscribes stores tariff information and the like.

In some embodiments, after the target file is successfully sent to the third device, determining whether to delete the target file according to the network storage subscription information of the user account of the third device may include:

and if the user account has the network storage authority, determining whether to delete the target file according to the storage condition information of the signed storage space of the user account and/or the condition information of the target file. And if the user account does not have the network storage authority, deleting the target file cached by the first device.

In the embodiments, whether a user account has a storage right of a network device is determined by a first device according to different network storage subscription information of the user account, when the user account has the storage right of the network device, whether the target file is deleted is determined according to storage state information of a subscription storage space of the user account and/or status information of the target file, and when the user account does not have the network storage right, the target file cached by the first device is directly deleted. In the process, the first device can perform different processing on the target file cached by the first device according to the network storage subscription information signed by the user, so that the user without the network storage authority can be prevented from additionally occupying network resources, and the legal rights and interests of the subscriber are guaranteed. Meanwhile, network resources can be reasonably distributed according to the requirements of users on the storage resources.

In some embodiments, determining whether to delete the target file according to the storage status information of the storage space signed by the user account and/or the status information of the target file includes at least one of:

when the residual capacity of a storage space signed by a user account is smaller than a first threshold value, determining to delete a target file cached by first equipment;

when the residual capacity of a storage space signed by a user account is smaller than a first threshold value, determining whether to delete a target file cached by first equipment according to the priority of the target file;

when the residual capacity of the storage space signed by the user account is larger than a second threshold value, determining to store a target file cached by the first device;

when the residual capacity of the storage space signed by the user account is smaller than a second threshold and larger than a first threshold, determining to store the thumbnail file of the target file;

wherein the second threshold is greater than the first threshold.

In these embodiments, the first threshold may be 10% and the second threshold may be 60%, and then when the remaining capacity of the storage space signed by the user account is less than 10%, it indicates that the capacity of the storage space signed by the user account is already used by more than 90%, at this time, the target file cached by the first device may be directly deleted, or whether the target file is deleted may be determined according to the priority of the target file, so that the storage space signed by the user account may be managed more flexibly, and unnecessary cache occupation is avoided.

When the residual capacity of the storage space signed by the user account is larger than 60%, the residual capacity of the storage space signed by the user account is still larger, and the target file can be directly stored. When the remaining capacity of the storage space signed by the user account is greater than 10% and less than 60%, it is indicated that the storage space signed by the user account has a smaller remaining space, and at this time, only the thumbnail file of the target file is saved, and the thumbnail file only contains part of the content in the target file. In the process, the first device can flexibly process the target file according to the residual capacity of the storage space signed by the user account, so that the target file is temporarily stored under the condition of avoiding unnecessary cache, the user can conveniently and directly acquire the target file next time, and the time delay of the user for acquiring the target file through network connection is reduced.

Based on the above, in some embodiments, the method further comprises:

after receiving the first request message, when determining that the first device locally stores the thumbnail file of the target file, acquiring the target file required by the third device from the second device based on remote connection, and simultaneously sending the thumbnail file to the third device.

In these embodiments, when it is determined that the first device locally stores the thumbnail file of the target file, the thumbnail file may be sent to the third device first, so that the user can view the thumbnail file, and after the first device acquires the target file, the target file is viewed. In the process, the time delay of waiting for receiving the target file by the user can be reduced.

Here, it should be noted that the first threshold and the second threshold are both examples, and in practical applications, specific data of the first threshold and the second threshold may be reasonably set according to needs of a user to meet different needs of the user.

In some embodiments, when the remaining capacity of the storage space subscribed by the user account is smaller than the first threshold, determining whether to delete the target file cached by the first device according to the priority of the target file may include:

For example, the user may prioritize the files according to whether the files are working files or entertainment files, and the like, such as setting the priority of the working files as a first priority, setting the priority of the entertainment files as a second priority, and prioritizing the files in an order that the first priority is higher than the second priority. The priority of the file can be extracted according to the content of the file, for example, for the file with the first priority, the content of the file can be the content related to work, and for the file with the second priority, the content of the file can be the content related to entertainment.

As another example, the user may prioritize files based on suffixes of the files, such as setting files suffixed with doc and pdf to a first priority and files suffixed with jpg and gif to a second priority, prioritizing the files in order of the first priority over the second priority.

Of course, the above is only an example, and in practical application, a user may perform priority setting on a file according to any mode to meet the use requirement of the user.

In these embodiments, when the remaining capacity of the storage space signed by the user account is smaller than the first threshold, it is indicated that the capacity of the storage space signed by the user account has been used by more than 90%, and at this time, if the priority of the target file is the first priority, it is indicated that the target file is important, so that the target file is saved, the next user can view the target file in time conveniently, and the time delay and the waste of network resources caused by reacquiring when the next user needs the target file are avoided.

In some embodiments, the method further comprises:

and deleting the files with the second priority of the target account number stored in the first device while storing the target file, wherein the second priority is lower than the first priority.

In the embodiments, the files with the priority lower than the priority of the target file are deleted while the target file is saved, so that the files with the higher priority can be saved preferentially, the files with the lower priority are deleted, more storage space is provided for the files with the higher priority, a user can conveniently obtain the files with the higher priority in time, and the obtaining time delay of the files with the higher priority is reduced.

Based on the above, in some embodiments, after receiving the first request message, acquiring, from the second device, a target file required by the third device based on the remote connection may include:

In these embodiments, the object file may be an object file acquired by a user, the first device may buffer the object file locally, when the first request message is received and the object file needs to be acquired, it may be determined whether the object file is locally stored, and if the object file is locally stored, the object file may be directly sent to the third device, without acquiring the object file from the second device based on a remote connection. And when the target file is not locally stored, the target file is acquired from the second equipment based on remote connection, so that network resources can be saved.

In some embodiments, after receiving the first request message, acquiring, from the second device, a target file required by the third device based on the remote connection, may further include:

after receiving the first request message, determining whether a target file specified and acquired by the first request message exists in the second device according to a storage directory and a file identifier of the second device locally stored in the first device;

and if the first request message specifies that the acquired target file exists in the second equipment, acquiring the target file required by the third equipment from the second equipment based on remote connection. If the first request message specifies that the acquired target file does not exist in the second device, the target file required by the third device does not need to be acquired from the second device based on remote connection, so that the waste of network resources can be avoided.

In these embodiments, the first device may have previously acquired the storage directory and the file identifier of the second device, and cached locally, so that, after receiving the first request message, it may be determined locally whether the target file specified to be acquired by the first request message exists in the second device, and then it may be determined according to specific situations whether the target file required by the third device needs to be acquired from the second device based on the remote connection, and when it is determined that the target file specified to be acquired by the first request message exists in the second device, the target file required by the third device is acquired from the second device based on the remote connection; and when it is determined that the target file specified to be obtained by the first request message does not exist in the second device, obtaining the target file based on the remote connection is not required.

In some embodiments, as shown in fig. 2, the method further comprises:

s201, receiving a storage directory and a file identifier of second equipment;

s202, receiving a second request message sent by third equipment;

s203, based on the second request message, the storage directory and the file identification of the second device are sent to the third device.

In these embodiments, the third device obtains the storage directory and the file identification of the second device by the first device communicating with the second device. The method is suitable for the situation that the first device and the second device cannot be connected in a short distance.

In other embodiments, when the distance between the third device and the second device allows, the third device and the second device may connect by acquiring a bluetooth address of the other device, so that the third device may directly request the storage directory and the file identifier of the second device from the second device.

In some embodiments, the third device may be a portable electronic device, and the second device may be an idle or unused electronic device placed in a certain place.

In some examples, the third device may be a cell phone that the user carries with him, and the second device may be an electronic device that the user is idle at home, such as a cell phone, a personal computer, an ipad, and the like.

In some embodiments, when the third device is a mobile phone carried by a user and the second device is an electronic device that the user is idle at home, such as a mobile phone, a personal computer, an ipad, or the like, and when the third device and the second device are connected through a bluetooth address of the other device to obtain the storage directory and the file identifier of the second device, the third device may first bind an app of the second device and then obtain the storage directory and the file identifier of the second device according to the app.

In a case that the third device binds the app of the second device, the second device and the third device may bind the app of the second device by acquiring a bluetooth address of the other party (specifically, a pairing key and an identification name of the other party may be acquired).

In other embodiments, when the third device is far away from the second device and cannot implement bluetooth connection, the third device may obtain the storage directory and the file identifier of the second device through the first device, and at this time, the third device may bind the app of the second device in a remote connection manner.

Specifically, the third device and the second device may share the same user account, the first device may obtain device information of the second device according to the user account, and the second device may be bound by selecting the device information of the second device.
