Embodiment Construction

[0024] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The embodiment of the present invention provides a file unlocking method, which is applied to electronic equipment, such as Picture 1-1 shown, including:

[0026] Step 101: Detect an unlock instruction for a target file to be unlocked from a list containing at least one file to be unlocked;

[0027] Step 102: Obtain the system type of the electronic device, enumerate the target file to be unlocked based on the system type of the electronic device to obtain a memory-mapped file handle, and generate a target file to be unlocked based on the memory-mapped file handle. File occupancy information;

[0028] Step 103: Based on the occupancy information of the target file to be unlocked, perform an operation to release the occupied state of the target file to be unlocked.

[0029] combine Figure 1-2 Further explai...

Abstract

The invention discloses a file unlocking method and an electronic device. The method comprises the steps of detecting an unlocking instruction for a target to-be-unlocked file in a list containing at least one to-be-unlocked file; based on a system type of the electronic device, at least performing memory-mapped file handle enumeration on the target to-be-unlocked file, and generating occupation information for the target to-be-unlocked file at least based on a memory-mapped file handle obtained by enumeration; and based on the occupation information for the target to-be-unlocked file, performing occupation state release operation on the target to-be-unlocked file.

Description

technical field [0001] The invention relates to file management technology in the field of information processing, in particular to a file unlocking method and electronic equipment. Background technique [0002] At present, the process of releasing the occupied state of a file mainly includes the following processing flow: firstly enumerate the occupied information of the file, and then check whether the selected file is occupied; when the selected file is occupied, obtain the corresponding occupancy information, and finally unlock the occupied file according to the occupancy information. [0003] In the above processing flow, enumeration of file occupancy information includes the following aspects: enumeration of file handles, enumeration of modules, and enumeration of memory-mapped files. However, the above-mentioned enumerated occupancy information still cannot adapt to a more comprehensive file unlocking scenario. Contents of the invention [0004] Embodiments of the...
