Description

Ways to generate file versions on the fly

The invention relates to a method for instantly generating file versions. The method is that in the process of editing a file by the user, the computer system can automatically back up the modified content of the file at different times, and store it in different versions. Either version file.

According to the generally known usage situation, after the user regularly modifies the file, he wants to keep the previous version of the file, and the specific method of managing different versions of the same file, please refer to Figure 1. This method is to use the user The files after each change are saved with different file names and stored in the folder of the computer system for future query. When the user needs to query a certain version of the file, open the folder and use The required version files, however, because of these different version files, the generation process must completely depend on the user and be stored manually. In this way, it will not only increase the workload of the user when doing this work, but also occupy a large of hard disk space.

And in existing known technology, although there is the time interval according to the user's own setting in Word, and the function of automatic archiving, yet, when storing because of this function at every turn, all use same file name (normal.dot) , therefore, the user cannot call and query the files modified before the final archive result.

In addition, even though Norton Ghout can fully back up the files within each set time to prevent the loss of file data. But this system can only carry out the action of backup at the time set by the user, and the time before the set time, and between the set time and the next set time, will not act. Therefore, there will still be cases of missing files. For example, if the user sets the action of backing up every ten minutes, then within ten minutes before the set time (the window period), if there is any modification to the file, the computer system will not perform any processing.

In view of some defects existing in the use of the above-mentioned traditional application software, the present invention provides an instant file version generation method.

An object of the present invention is to provide an instant file version generation method. The method mainly enables the computer system to store the modified content of the file at different times in real time during the process of editing a certain file by the user, so as to generate different versions of the file. The computer system can call different versions of files at any time according to the requirements of users.

Another object of the present invention is to provide a method for generating instant file versions. The computer system can automatically delete the stored older version files according to the user's settings, and only store the new version files. Cause the space waste of storage device (such as hard disk).

Another object of the present invention is to provide a method for generating instant file versions, which does not need to design independent modules for different software, but completes the generation of version files in the same way, and stores them in a predetermined location. It is versatile.

The real-time version generation method of the present invention mainly intercepts the operation information written by the user when editing the file through the hook function (Hook), and makes different processing methods according to the comparison result. Please refer to shown in Figure 2, this method is mainly that when the user edits a certain file, the computer system will save the original content of the file (101), and at the same time through the hook function (Hook) in the interception module, the The modified content of the file is intercepted, and the intercepted content is stored in the user-defined function unit for calling (102).

Then the modified file (hereinafter referred to as the new version file) stored in the self-defined function unit and the file (hereinafter referred to as the old version file) originally stored in the computer system are sent to the comparison module for comparison, so that the comparison module can be obtained from Three different directions, such as file size, file saving date, and the cyclic redundancy check value (CRC) of the data contained in the file, are compared (103) respectively, if the result of comparing the old and new version files is different, then the new Version file is sent in the backup module (104), is backed up, and generates new file; If the result of old and new version comparison is identical, then store (105) with the original title (File Name) of this file.

Furthermore, the process of receiving and processing user information by the method of the present invention will be described in detail as follows in conjunction with the accompanying drawings (please refer to FIG. 3 ):

First, when a user is editing a file, the computer system will intercept the file that the user is operating (201), and wait to receive the operation information (202) that the user writes into the file, and when the computer system receives the operation information , that is, the file to which the operation information is written will be identified (203), and it is judged whether the file in which the operation information is being written is a file specified by the user in advance (204). If the result of the judgment is that the operation information is being written If the imported file is not the file specified by the user, then the computer system is invoked to continue editing the file (208).

If the file is the file specified by the user, compare the file with the previous version content of the file (205), so that the computer system can judge whether there is any change between the two by the comparison result between the two (206), If there is a change, the computer system will back up the file and store it in the specified location to generate a new version of the file (207); if the file has no change compared with the previous version of the file, the computer system will call Continue the original editing action of the file (208).

As for the relevant processes of the above-mentioned interception module, comparison module and backup module, in conjunction with the accompanying drawings (please refer to Figures 4, 5, and 6), further details are as follows:

1. Interception module process:

Please refer to shown in Fig. 4, at first, computer system can call the hooking function (for example: IFSMgr-InstallHook () function) (301) in the intercepting module; Preserve the function address (302) corresponding with this file previous version simultaneously; Afterwards Embed a custom function address (303) in this address; judge whether this custom function address is embedded successfully (304); The self-defining function is called (306), so that the computer system calls the self-defining function, and when calling the self-defining function for interception processing, the self-defining function will intercept the file in the function address embedded with it (307).

2. Compare module flow:

Please refer to shown in Fig. 5, at first, this comparison module can be compared (401) with the size of the previous version of this file (hereinafter referred to as old version file) with the size of the file (hereinafter referred to as new version file) intercepted by the interception module, And judge whether there is change (402) by comparison result, if there is change, then back up the file (being new version file) of this operation in progress, so, can obtain the latest version (408) of this file; If file size does not change, Then continue to compare the file date (403) of the old and new versions, judge whether it has changed (404), if there is a change, then back up the file in operation, and use the current operation date of the file in operation as the latest version The name of the file (408); if the date of the file of the old and new versions still does not change, then compare the cycle redundancy check value (Cycle Redundancy Check, referred to as CRC) (505) (505) of the two, and judge whether the value changes (406) , if there is a change, the computer system backs up the file being operated (408), if there is no change, the computer system does not do any processing, and ends the processing program (407).

3. Backup module process:

Please refer to shown in Figure 6, at first, computer system can judge whether the content of the file being operated changes (501), if there is no change, then end the relevant processing procedure; , compared with the maximum value set by the user (502), the computer system can judge whether the total number of files of the saved file version has exceeded the maximum value (503) set by the user by the comparison result, if it exceeds the set If the specified maximum value is specified, then the computer system will remove the older version of the file, and only keep the latest file version (504), and then continue to read the file being operated (505), otherwise, the computer system will directly read the file being operated. After the file (505), convert the current operating time (506) of the operating file into a string form (507), create a new folder (508), and then copy the file to the new folder (509) In this way, the computer system can periodically remove the old version of the file according to the user's request, so as to achieve the purpose of freeing (free) the space of the storage device (such as a hard disk).

In order to further understand the present invention, an example is given below to illustrate as follows:

The method for automatically generating file versions in real time of the present invention is a file backup computer system, which can automatically store the files backed up each time in different versions when the user edits the files. The specific method is to store the files that need to be backed up in different periods with the date and time of the file being stored as the directory name of the file when backing up the file.

Please refer to Figure 7. For example, a file was modified at three different times: 4:20pm on August 26, 1999, 3:20pm on August 26, 1999, and 8:30am on August 27, 1999. , if the user wants to keep these three version files, the usual way is to manually enter different directory names, and store the three files with different file names.

However, the present invention only needs to intercept the file being operated by the user through the hook function (Hook), and at the same time of interception, identify the user's current copy operation to the file, compare whether the file content has changed before and after the write operation, and find that the 1999 At 4:20pm on August 26, the content of the file modified by the user changed, that is, read the computer system time of the currently stored file, convert it into a string, and create a new folder based on these strings. The new folder The name of the file is set to this string, and the current version of the file is automatically copied to the folder named 8/26/99/4:20pm. The file version modified at 8:30am on the 27th will be automatically backed up in the folders of 8/26/99/3:20pm and 8/27/99/8:30am in the same way as before, so that users can query in the future .

Furthermore, the computer system can compare the total number of versions stored in the folder (12 in this embodiment) according to the user's settings (10 in this embodiment), and compare the total number of versions stored in the folder The previous 10 versions stored are deleted, while the latest 2 versions are kept (as shown in the dotted box).

To sum up, the instant file version generation method of the present invention can not only improve various shortcomings of the known technology, but also improve the efficiency in use and is practical.
