Method for instantaneous generation of file version

Abstract

A method for instantaneously generating file version includes such steps as intercepting the file being operated by user, comparing it with its previous version just before this version, judging if the variation exists, backing up the file if there is variation, and storing it to pointed addresses to generate new version. The older version can be automatically deleted according to user requirement.

Description

technical field [0001] The present invention is a method for generating file versions in real time. In the process of editing files by users, the computer system can automatically back up the modified contents of the files at different times and store them in different versions. The computer The system can call any version of the file stored in the storage device according to the needs of the user. Background technique [0002] 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 As shown, the method is to save the files changed by the user each time with different file names, and store them in the folder of the computer system for future query. When the user needs to query a certain version of the file , and then open the reading folder, and use the required version files. However, beca...

[0002] 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 As shown, the method is to save the files changed by the user each time with different file names, and store them in the folder of the computer system for future query. When the user needs to query a certain version of the file , and then open the reading folder, and use the required version files. However, because of the different version files, the generation process must be completely dependent on the user and stored manually. In this way, it will not only increase the user's work The workload of this work will take up a lot of hard disk space

[0003] In the existing known technology, although there is a function of automatic archiving according to the time interval set by the user in Word, the same file name (normal dot) is used for each storage because of this function. , therefore, the user cannot call and query the modified file before the final archive result

[0004] In addition, although Norton Ghout can fully back up files at each set time to prevent file data loss, the system will only perform backup actions at the time set by the user, and at the set time There will be no action between the set time and the next set time, so there will still be missing files
