Abstract

The invention relates to a method and a device for cleaning data. The method comprises the following steps: determining whether the difference between a latest access time and a current time of to-be-cleaned data stored in a current scan node in a data structure, which comprises a plurality of nodes and is used for saving latest access time and document information of to-be-cleaned data, is greater than a preset threshold or not; determining whether the to-be-cleaned data stored in the current scan node in the data structure is in a white list or not if the difference is greater than the threshold; continuing to scan the next node in the data structure if the corresponding to-be-cleaned data in the current scan node in the data structure is in the white list; and cleaning the corresponding to-be-cleaned data in the current scan node if the corresponding to-be-cleaned data in the current scan node in the data structure is not in the white list. By adopting the technical scheme, the memory space of a system can be released, and the running speed of the system can be promoted.

Description

technical field [0001] The present disclosure relates to the technical field of computer processing, in particular to a data cleaning method and device. Background technique [0002] At present, after installing a large amount of software on the terminal, there will be a large number of temporary files and file directories. After a period of accumulation, if the mobile phone is not cleaned up, the running speed of the mobile phone will decrease. At the same time, in the file browser, it will also appear very clutter, and finding files becomes difficult. A common cleaning method is to regularly count the usage frequency of application software, and search for application software whose usage frequency is lower than a predetermined value according to the statistical results; determine whether there is an alternative software for the application software whose usage frequency is lower than a predetermined value, and if , prompting the user to delete the application software wh...
