Problems solved by technology

[0004] However, the database based on the existing storage space cleaning method is a relational database, which makes the method need to combine all the characters of the path information of the scanned directory with all the records stored in the database during the directory scanning process. The path information is compared and matched one by one (that is, traversed), and the mobile terminal needs to generate a SQL (Structured Query Language, Structured Query Language) query statement according to the full path information of the scanned directory, and the generated SQL query statement is relatively long (dozens of k), which makes the query efficiency of the database low, resulting in slow cleaning speed. The intuitive reflection is that the user waits for a long time to clean up, which affects the user experience

Abstract

The embodiment of the invention discloses a method for cleaning memory space based on a prefix database and a device thereof, and the method comprises the following steps of: scanning the memory space and acquiring path information of currently scanned catalogues; extracting prefix information from the path information; searching the prefix information matched with the extracted prefix information from the prefix database; comparing the path information of the prefix information searched from the prefix database with the acquired path information; if comparative results are the same, collecting garbage to the currently scanned catalogues according to cleaning strategies corresponding to the path information in the prefix database. When the memory space is cleaned, the path information of the currently scanned catalogues isn't compared and matched with all records in the prefix database so as to improve the query efficiency of the database, quicken the cleaning speed of the memory space and promote the user experience.

Description

technical field [0001] The present invention relates to mobile terminal technology, in particular, the present invention relates to a storage space cleaning method and device based on a prefix type database. Background technique [0002] At present, the functions of mobile terminals are increasingly powerful, and users can install software such as chatting, surfing the Internet, games and entertainment in the mobile terminals. As the user continues to use the mobile terminal, there will be more and more junk files in the storage space of the mobile terminal. These junk files usually include junk files generated during the operation of the mobile terminal system, as well as cache files generated during the operation of applications installed on the mobile terminal, invalid old version installation packages due to software version upgrades, and software uninstalled by users. Some application residual files and so on generated after. If these junk files are not cleaned up in ...
