Problems solved by technology

[0004] After the software is upgraded, the installation directory of the software in the registry will be updated to the installation directory of the new version, so the existing garbage cleaning software will only search for junk files in the installation directory of the new version, while the installation directory of the old version cannot Junk file search, which undoubtedly reduces the effect of garbage search
Since the junk files in the installation directory of the old version exist in the terminal device for a long time and take up disk space, it affects the efficient operation of the terminal device

Abstract

The embodiment of the invention provides a method and system for searching for a useless file. An older-version application program installation directory meeting an installation directory feature corresponding to the application program in a preset feature library besides the installation directory in the parent directory of the application program installation directory obtained according to a registry, and the useless file is searched for in the searched older-version application program installation directory. Due to the fact that the new-version and older-version application program installation directories generally have a certain installation directory feature, the older-version application program installation directory can be found through the installation directory feature, and therefore the useless file is searched for in the older-version application program installation directory. Therefore, according to the method and system for searching for the useless file, the useless file search effect is improved, the situation that the useless file in the older-version installation directory exists in terminal equipment for a long time and occupies the disk space is avoided, and efficient operating of the terminal equipment is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of garbage information search, in particular to a garbage file search method and system. Background technique [0002] With the development of technology, there are more and more application programs on terminal devices. [0003] The garbage cleaning software can search for junk files on the terminal device, so as to clean up the found junk files according to the user's cleaning instructions. Existing garbage cleaning software obtains the installation directory of each software from the registry and searches for garbage files in the installation directory of each software when searching for garbage files. With the continuous upgrade of software, some software does not delete the installation directory of the old version when the version is upgraded, which causes the installation directory of the new version and the installation directory of the old version of these software to exist in the terminal device a...
