Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
For mobile terminals such as the mobile phones in solution conventional art because the technical problem of the effective rate of utilization deficiency of the phone memory that mobile phone EMS memory is limited and the storage method of download file causes, spy proposes the method for a kind of file storage.The realization of the method can be dependent on computer program, and this computer program can run on the computer system based on von Neumann system.This computer program can be the application program of the application program of file download application or file management application.This computer system can be run the such as intelligent terminal such as smart mobile phone, panel computer of above computer program.
Concrete, as it is shown in figure 1, the method for above-mentioned file storage comprises the steps:
Step S102: detection file write operation, obtains file size corresponding to described file write operation and file type.
File write operation is that file or data are write hard disk or the operation being saved in internal memory by terminal CPU, detect when other devices in the incoming file of external equipment or terminal send or generate file at terminal CPU, terminal CPU can receive file write instruction, namely being equivalent to trigger file write operation, now terminal can detect the write operation of above-mentioned file.
Further, in the present embodiment, file write operation include receiving file by network, storage device write operation when being generated file by the incoming file of I/O equipment and/or application.
Concrete, terminal downloads file by the application foradownloaded video on network or terminal, song etc., and namely the download of this download file is equivalent to trigger file write operation；Again such as, terminal CPU detects by other equipment by input/output end port (I/O) incoming file, then this incoming file is written in the equipment specified by I/O equipment, in this process, the incoming file of I/O equipment detected namely be equivalent to detect the file write operation of this incoming file；Again such as, in terminal, mounted application program can generate history file or other cache files etc. in the process used, these files are also required to store in terminal, as, install and the WeChat software on mobile phone, the historical data of chat record can be generated with good friend when user chats, this historical data can be saved in mobile phone, therefore, when user uses above-mentioned WeChat application to produce historical data, the CPU of terminal needs this history data store in the storage device of terminal, namely CPU is when the file generated of above-mentioned historical data being detected, also correspond to detect the file write operation of the file corresponding to above-mentioned historical data.
When file write operation being detected, obtain the relevant information carried in this operational order, for instance the information such as the filename of file to be written, file size, file type, namely obtain filename corresponding to above-mentioned file write operation, file size, file type etc..
Such as, file type includes at least one in video, audio frequency and picture.Concrete, for mobile phone, main storage file, except the program file of system and application program, is mainly the photograph/picture etc. of video, audio frequency and the shooting/reception downloaded.In the present embodiment, file type can obtain according to file extension, for instance, the file of file extent " .mp4 " by name is video file, and the file of file extent " .jpg " by name is picture file.
In the present embodiment, for needing the file size of file of storage to carry out anticipation, for the memory space shared by file bigger time, this document is written in the SD card of terminal, rather than is stored in that terminal is limited and in valuable internal storage space.Concrete operation is referring to step S104 and step S106.
Step S104: when described file size is more than or equal to threshold value, is set to the peripheral hardware storage device preset by the root store path of file corresponding for described file write operation.
Step S106: when described file size is less than described threshold value, is set to the terminal inner memory area preset by the root store path of file corresponding for described file write operation.
Above-mentioned threshold value is the value arranged previously according to mobile phone EMS memory, and the storage position being used for defining file to be written is terminal inner memory area or peripheral hardware storage device.For example, it is possible to above-mentioned threshold value is set to 5MB, say, that when the file size of file to be written is more than or equal to 5MB, this document is stored in the peripheral hardware storage device of terminal, namely in SD card；When file size is less than 5MB, directly this document is stored in the internal storage areas of terminal, namely in internal memory.
Root store path refers to path or the catalogue of the most upper level in file storage path.Such as, when file is stored in the memory area that C dish is corresponding, the root store path of its correspondence be " C: ".In the present embodiment, the root store path of the mobile terminals such as smart mobile phone is broadly divided into terminal inner memory area (i.e. internal memory) and the peripheral hardware storage device (i.e. SD card) preset, if being called C dish and D dish, then corresponding root store path is " C: " and " D: ".
As it was previously stated, when the file size of file to be written is more than or equal to 5MB, be SD card by root store path equipment, namely " D: "；When the file size of file to be written is less than 5MB, root store path is set to internal memory, namely C: ".
It should be noted that in the present embodiment, arranging of threshold value can also be arranged according to file type, for instance, 5MB is a bigger value for picture file, but for video file, 5MB is sized to a less value.Concrete, after step s 102, this method also includes: obtain the storage threshold value corresponding with described file type, and step S104 particularly as follows: when the storage threshold value that described file size is corresponding more than or equal to described and described file type, be set to the peripheral hardware storage device preset by the root store path of file corresponding for described file write operation；Step S106 particularly as follows: when the storage threshold value that described file size is corresponding less than described and described file type, be set to the terminal inner memory area preset by the root store path of file corresponding for described file write operation.
In being embodied as, it is possible to arranging the file type storage threshold value corresponding with picture is 0.5MB, the file type storage threshold value corresponding with video file is 10MB, and the file type storage threshold value corresponding with audio file is 3MB, and the storage threshold value of alternative document type is 5MB.It should be noted that the setting of above-mentioned threshold value or the storage threshold value corresponding with file type, it is possible to being the default setting of system, user can also be configured according to the memory headroom size of terminal and user's request or revise.
Also, it should be noted be written in the process of disk being written into file, it is also possible to the phenomenon that the remaining space of disk is not enough occurs, therefore, in the present embodiment, when arranging the root store path of file to be written, in addition it is also necessary to the residual memory space of consideration disk corresponding to root store path.
Concrete, in one embodiment, in step s 102, after obtaining the step of file size corresponding to described file write operation and file type, before step S104 and step S106 arranges the step of root store path of file to be written, this method also includes: obtain the residual memory space size of described terminal inner memory area, it is judged that whether described file size is more than the residual memory space size of described terminal inner memory area；If so, then the root store path of file corresponding for described file write operation is set to described default terminal inner memory area, performs the step of the relative store path preset corresponding to the described file type of described acquisition.
That is, when the file size that needs store is more than the residual memory space size of terminal inner memory area, do not consider further that the file size to file to be written in step S104 and S106, directly the root store path of this document is set to the peripheral hardware storage device preset.It addition, when above-mentioned file size is less than or equal to the residual memory space size of terminal inner memory area, in addition it is also necessary to whether file size is exceeded threshold value and accounts for, namely perform step S104 or S106.
It should be noted that, in the consideration of the residual memory space of the disk corresponding to root store path, that be much larger than the memory space of tag memory in general due to the memory space of terminal peripheral hardware storage device and can carry out upgrading or dilatation, if file to be written is because the reason of file size cannot complete the write operation in terminal peripheral hardware storage device, it generally also can be failed in the write operation of tag memory, now unsuccessfully also imply that the memory space taken required for this document is also bigger in the write of terminal peripheral hardware storage device, therefore, in the present embodiment, only consider that whether the file size of file to be written is more than terminal inner memory area.
Step S108: obtain the relative store path preset that described file type is corresponding.
Relative store path refers to that file clips to the path of this document process from the file at root store path place, such as, be stored in the file " 123.jpg " under the WeChatfile in the programfiles file in C dish, its storage address be: C: programfiles WeChatfile；To file " 123.jpg ", its root store path be " C: ", relative store path is " programfiles WeChatfile ".
In the present embodiment, in order to facilitate user to carry out file management, the file that user downloads is classified according to file type, and is stored in the file corresponding with file type, such as, file type is that the All Files of video file is stored in the file corresponding with video file type.In the internal storage areas and peripheral hardware storage device of terminal, create corresponding file according to file type, such as video file folder, Photo folder etc..
In this step, according to the file type that file write operation is corresponding, default file type with in the corresponding relation of relative store path, search the relative store path corresponding with this document type, this relative store path be this file to be written target storage address in relative store path.
Step S110: write file with described relative store path according to described store path.
Concrete, the storage address of file is made up of with relative store path root store path, when root store path all obtains with relative store path, it is possible to what obtain this document specifically stores address.Such as, the root store path obtained in step S104 or step S106 be " D: " and what obtain in step S108 is " musicfile " with store path, then the storage address of this document or writing address are: D: musicfile.According to this storage address or writing address, file corresponding for the file write operations detected in step S102 write this address, or the file detected in step S102 is saved in this address.
In one embodiment of the invention, optional step also includes: in step S110: also include before writing file according to described store path and described relative store path: generating file write prompting message according to described file and described store path, described relative store path and show, described file write message is for pointing out the storage address of file described in user；Detection user writes the confirmation instruction of prompting message input for described file, performs step S110: write file according to described store path with described relative store path.
Concrete, preserve or before file write at file, the address that this document is about to write is showed user, finally store address with what point out user's this document.It is to say, obtain the storage address of this document according to described store path of file, described relative store path, and generate file write prompting message.Such as, this document write prompting message can be: file 123.jpg is saved in C: picturefile.
Further, before step S110, namely before file write, it is necessary to user confirms, only just performs the write operation of file after user confirms, namely just performs above-mentioned steps S110 after the confirmation instruction that user inputs being detected.
Concrete, write the displaying interface of prompting message at above-mentioned file, user writes prompting message for above-mentioned file, clicks " confirmation " button shown on interface, or input the operation corresponding with confirming instruction, be namely equivalent to input such as corresponding with file write information confirmation instruction.
Above-mentioned steps S102 to step S110, make terminal in the process downloading file or file write, as far as possible few occupy the memory headroom that terminal is limited, bigger file is stored in the peripheral hardware storage device of terminal, because the memory space of peripheral hardware storage device is generally larger than the memory space of tag memory, and can carry out upgrading (such as, change the SD card of bigger memory space, or increase a SD card to increase memory space), but the memory space of tag memory or it is possible that the phenomenon of deficiency, at this moment, it is accomplished by user deleted by the file in internal memory or be transferred to peripheral hardware storage device.
Concrete, as in figure 2 it is shown, a kind of method that Fig. 2 illustrates file unloading, specifically include following steps:
Step S202: obtaining file unloading instruction, the root store path of the file that described file unloading instruction is corresponding is terminal inner memory area.
File unloading instruction is the unloading instruction that user is inputted for certain file by terminal, it is intended to be changed storage address or the storage position of this document, in the present embodiment, refer in particular in the peripheral hardware storage device that the file that will be stored in terminal inner memory area (i.e. tag memory) dumps to terminal, namely treat unloading file be terminal inner memory area with store path, namely treat that the file of unloading is the file being stored in tag memory.
It should be noted that in the present embodiment, the file corresponding with above-mentioned file unloading instruction can be the file of any file type of video file or picture file or other, it is also possible to is file, for instance is stored in the video file folder in tag memory.
Step S204: obtain the relative store path of target that the relative store path of file corresponding to described file unloading instruction is corresponding.
Step S206: with described peripheral hardware storage device for root store path, stores position for the purpose of store path in conjunction with described target and moves the file that described file unloading instruction is corresponding.
Namely the file corresponding with file unloading instruction treat unloading file, and the relative store path of this document is the relative store path corresponding with root store path in the storage address of this document.Such as, treat that the storage address of unloading file is: C: videofiles, then the relatively storage address of this document is: videofiles.
In the present embodiment, in the internal storage areas and peripheral hardware storage device of terminal, it is respectively created identical or corresponding file, in the internal memory of mobile phone and SD card, is namely respectively created identical or corresponding file.Such as, be respectively created in internal memory and SD card storage video file video file folder, and arrange its relative store path be videofiles.Again such as, create in internal memory the video file folder of storage video file for videofiles, video file in SD card folder be TVshowfiles.
In being embodied as, terminal is carrying out when the unloading of unloading file, directly will treat that unloading file is transferred to treat the corresponding folder in the SD card that unloading file file at place in internal memory is corresponding with this in internal memory.As it was previously stated, the corresponding file file in the videofiles file in internal memory being transferred in SD card: videofiles file.
Therefore after getting the relative store path treating unloading file, obtaining the relative store path in the SD card that store path relative to this is corresponding is the relative store path of target, and this target is this relative store path treating that unloading file stores in SD card relative to store path.Namely treat that the purpose storage position of unloading file unloading is root store path by with peripheral hardware storage device, forms for root store path with the relative store path of target.Store position according to above-mentioned purpose and file unloading instruction will treat that unloading file carries out unloading.
It should be noted that, above-mentioned steps S202 is the method for the peripheral hardware storage device that the file in terminal inner memory area or file dump to terminal to the method for the file unloading described in step S206, otherwise, the file dump method that the file of storage in terminal peripheral hardware storage device dumps in terminal inner memory area can also similar be processed, but in general, the internal storage areas of terminal is limited, for a user, it is typically all and the file in terminal inner memory area is deleted or unloading is to save terminal inner memory area, and the file that seldom will be stored in the peripheral hardware storage devices such as SD card dumps to terminal inner memory area.
In addition, for solving the mobile terminals such as mobile phone in conventional art because mobile phone EMS memory is limited and downloads the technical problem that the effective rate of utilization of the phone memory that the storage method of file causes is not enough, in one embodiment, as shown in Figure 3, spy proposes the device of a kind of file storage, including 102, first store path of write operation detection module, module 104, relative store path acquisition module 106 and file writing module 108 are set, wherein:
