Fig. 2 is the application software flowchart of synchronously renewing file of the present invention.
Embodiment
See also Fig. 1, the method for described synchronously renewing file of the present invention is applicable between data processing main frame 200 and the coupled equipment 400.
The method that the present invention upgrades the flash memory device file synchronously is by at data processing main frame 200 or equipment 400 ends specific application software being set, automatically the file or folder of appointment is carried out the data synchronization backup between data processing main frame 200 and coupled equipment 400 by application software, described data can be upgraded operation at data processing main frame 200 or equipment 400, and the position of data manipulation just is not subjected to the restriction of backed up in synchronization.
Data processing main frame 200 general references are various to have data-handling capacity and operating system thereof to support the electronic equipment that external unit inserts, and includes but not limited to various personal computers, small-size computer, data processing work station and various exclusive data disposal system with external memory function.
Described equipment 400 is the flash memory devices that refer to an access data processing main frame 200, generally include but be not limited to flash disk and various FLASH mobile memory card based on the Flash medium, as compact flash (CompactFlash card), small intelligent medium memory card (SmartFlash card), multimedia card (Multimedia Card), safe digital card (Secure Digital Card) and memory stick (MemoryStick) etc., and based on the portable hard drive of other storage mediums, described storage medium comprises Mram (MRAM), DRAM, SDRAM, EPROM, EEPROM or SRAM etc.
Be that example describes synchronous updating method of the present invention as equipment 400 now with flash disk, the present invention about the back mechanism of the synchronously renewing file of flash disk comprise with flash disk as the backup target machine, adopt main frame to judge the backup target machine as the backup target machine and according to the time that file produces.According to the setting that is arranged on the application software in the flash disk, the user can select a kind of mechanism or several mechanism mode of making synchronously renewing file wherein.Should three kinds of back mechanisms describe respectively below.
Adopt flash disk as back mechanism be meant the user through be everlasting with flash disk that main frame is connected on file is carried out data manipulation, updating file, adopt this back mechanism, the built-in application software file on will the default flash dish is a latest document in the flash disk, be called source file, as long as modification has taken place in the file on the flash disk, through with main frame in the corresponding synchronous file stored compare, the source file of storing in the flash disk and the synchronous documents of host stores are inconsistent, then with this corresponding file under synchronous documents or the synchronization folder on the covering of the source file on the flash disk main frame.If the file in the flash disk is a new files, through comparing, in main frame, do not find the corresponding synchronous file, application software is directly carried out a replicate run, should new file copy store under the corresponding synchronous file to the main frame, as do not have synchronization folder, and then point out the user newly-built synchronization folder, store.
Adopt the mechanism of main frame as backup, the mechanism of its backup is machine-processed opposite with the flash disk backup, major different is, adopt the mechanism of main frame as backup, the file that built-in application software is understood on the default host in the flash disk is a latest document, claim source file, when the user makes modification to the arbitrary file under synchronous documents on the main frame or the synchronization folder, as long as the user plugs main frame with flash disk, built-in application software will remove to detect synchronous documents in the main frame or the corresponding file under the synchronization folder in the flash disk, through with flash disk in the corresponding synchronous file stored compare, be modified if find, then application software will be carried out a replicate run, and the ancient deed with in the modified new file covering flash disk in the main frame backs up the synchronous documents in the main frame.If the file in the main frame is a new files, through relatively, in flash disk, do not find the corresponding synchronous file, application software is directly carried out a replicate run, should new file copy store to flash memory.
In aforementioned two kinds of back mechanisms, application program can adopt the big or small mode of time, file content or the file of the generation of comparison file to judge whether synchronous documents and comparison file have difference to the detection of synchronous documents.
The employing time is as the mechanism of backup, this mechanism is to utilize in the computer, the foundation of All Files and modification all indicate if having time, the time of file all is that time with last modification is as the up-to-date time, can go to check the file modifying time by application software, confirm latest document, adopt this mechanism, in the flash disk that built-in application software is no longer given tacit consent in the flash disk with main frame in which file be new file, but will compare file in the flash disk and the corresponding synchronous file in the main frame, replace the corresponding synchronous file of previous generation with the file of up-to-date generation.If application software finds a file in flash disk or in the main frame, and when not finding the corresponding synchronous file in main frame or flash disk, then application software is directly carried out a replicate run, and this document is duplicated.
See also Fig. 2, synchronously renewing file method of the present invention is to utilize a specific application software to be set in flash disk to go to automatically perform, when the flash disk that will be provided with this application software step 102 user inserts host computer system for the first time, in step 103, this application program can automatically perform to detect in the main frame whether carried out configuration effort, promptly detect whether synchronous documents or synchronization folder are arranged, if application program is not found the corresponding synchronous file in main frame, just be configured step 104 prompting user, promptly selected one or create the synchronization folder of a new file as equipment, and dispose corresponding back mechanism.
The setting of synchronous documents or synchronization folder need not specific (special) requirements, only need in the storage space of main frame, to specify access path and file or folder name to get final product for the application software that is arranged in the flash disk, the access path of this appointment and file or folder name are employed program and preserve, and are convenient to application program and discern this synchronous documents or synchronization folder according to the path of this appointment and filename or file.
If application software finds that main frame has carried out the configuration of synchronous documents, then application software detects the back mechanism of respective synchronization file or synchronization folder, application software at first judges whether to adopt flash memory as back mechanism in step 105, if this synchronous documents or synchronization folder are to adopt flash memory as back mechanism, whether then detect file in step 106 is modified, if file is modified, then step 107 with flash disk on file be copied under the synchronization folder on the main frame.
If the application software detection obtains the respective synchronization file or synchronization folder is not to adopt flash disk as back mechanism, then whether adopt main frame as back mechanism at step 108 this synchronous documents of detection or synchronization folder, if this synchronous documents or synchronization folder are to adopt main frame as back mechanism, whether then detect file in step 109 is modified, if file is modified, then step 110 with main frame on the file copy of synchronous documents to flash disk.
If it is not to adopt main frame as back mechanism that application software detects the respective synchronization file or the synchronization folder that obtain, then whether adopt the time that produces with file as back mechanism at step 111 this synchronous documents of detection or synchronization folder, be not to adopt the time that produces with file as back mechanism if judge in step 111, then detect and finish in step 113 application program, if at this synchronous documents of step 111 or synchronization folder is to adopt the time that produces with file as back mechanism, then at the further relatively file and the synchronous documents of main frame in the flash disk of step 112, with the old file of file replacement of new generation.
More than be that execution flow process about the application software of Fig. 2 is the concrete execution flow process of application software among the present invention, application software is not limited to above-described order to the detection of the back mechanism of synchronous documents or synchronization folder, just application software can detect with any in proper order to above three kinds of back mechanisms, need to prove in the process that aforesaid application software detects, synchronous documents or synchronization folder have just selected to set wherein a kind of in three kinds of back mechanisms, certainly application software also can only be set a kind of back mechanism, provides the user selected.
See also Fig. 1 again, the present invention can coexist in many ways about the back mechanism of synchronously renewing file, for with the coexistence of multiple file backup mechanism the time, except in main frame 200, setting up the different synchronization folder according to different back mechanisms, as flash disk backup area 210, main frame backup area 220 and latest document backup area 230, also in flash disk 400, set up and the corresponding synchronization folder of main frame synchronization folder: flash disk backup area 410, main frame backup area 420 and latest document backup area 430.
Shown in Figure 1 is with the embodiment of three kinds of back mechanisms coexistences, and according to the back mechanism of the synchronous renewal that application software provided, any two kinds of can select in above-mentioned three kinds of back mechanisms of user make up.Adopt multiple back mechanism coexistence to provide wideer choice for the user.
When in the flash disk a plurality of synchronization folder being arranged, application software detects the execution flow process of each corresponding synchronization folder in the main frame according to application software shown in Figure 2 successively according to synchronization folder set in the flash disk, and judges the back mechanism of each synchronization folder.
Described application software can be detected and back up synchronous documents the detection of synchronous documents by the manual application program that activates, in addition, it is the cycle that application software can also be set certain time interval to the detection of synchronous documents, synchronous documents is carried out the detection and the backup in cycle.
Described application software also is provided with the function of soft unlatching, when the user does not need backed up in synchronization, can turn off application software, and after application software was switched off, it is the same with existing flash disk that this flash memory disk is deposited, and can not carry out synchronous renewal or backup to corresponding file.
Satisfy the user file has been carried out the demand of backed up in synchronization by specific application software is set in flash disk, shortened the manual time of user, improved work efficiency effectively, reduced the possibility of maloperation.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvement and distortion, these improvement and distortion also should be considered as falling into protection scope of the present invention.
