Embodiment 1

[0063] refer to figure 1 , showing Embodiment 1 of a file deletion method of the present application, including the following steps:

[0064] Step 101, intercepting the call of the operating system to the original function for realizing file deletion.

[0065] When a user deletes a file, he will send a delete request to delete the target file to the operating system, and the operating system will call the corresponding function to perform the delete operation.

[0066] There are many ways to intercept, and the deletion request can be intercepted by intercepting the file operation process of the operating system, etc., or intercepted by the file filter driver. For example: redirecting the function address, that is, pointing the original function address of the operating system in the memory to implement the delete operation to the address of the interception function provided by this application.

[0067] Taking the Windows operating system as an example, the original function ...

Abstract

The invention provides a method for deleting a file. The method includes steps: intersecting calling of an original function for deleting the file from an operating system; obtaining file characteristics of the target file to be deleted from the intersected calling, judging whether the file characteristics are in a stored range of non-deletable file characteristics or not, stopping the calling and giving out reminding information of the file characteristics are in the stored range, and carrying out a next step if the file characteristics are not in the stored range; and releasing the intersected calling of the original function for deleting the file from the operating system. The invention further provides a system for deleting the file. By the aid of the method for deleting the file and the system for deleting the file, a user can be correspondingly prompted when deleting the file, and mistaken deletion of files in the operating system is avoided.

Description

technical field [0001] The present application relates to the technical field of computer data processing, in particular to a file deletion method and system. Background technique [0002] When users manage files in the computer, they usually need to delete files in the disk. Generally, the deletion operation of the user is realized through the deletion function of the operating system itself. [0003] However, not every user is familiar with each file in the operating system, and does not know the purpose of some files. Therefore, if the user does not turn to a professional for help when manually deleting files, it is easy to delete them by mistake. For example, files that should not be deleted, such as system files or special directory names, may cause system instability or other adverse effects if they are deleted. Contents of the invention [0004] The present application provides a method and system for deleting files, which can solve the problem of files being dele...
