Abstract

The embodiment of the invention discloses a cache file recovery method and device, electronic equipment and a storage medium. The method comprises the following steps of: when an executable file is loaded into the memory, judging whether the executable file is an important cache file or not according to the attribute information of the executable file, marking the executable file if the executablefile is the important cache file, judging whether the residual capacity of the memory meets a preset condition or not, and recycling the unmarked cache file in the memory if the residual capacity ofthe memory does not meet the preset condition. When a user uses the electronic equipment, important cache files and high-frequency access files can be generated in a memory of the electronic equipment, and the unimportant cache files and the non-high-frequency access files are recovered by judging the residual capacity memory of the memory, so that the important cache files are reserved, and the access speed of the files is increased.

Description

technical field [0001] The present application relates to the technical field of file management, and in particular to a method, device, electronic equipment, and storage medium for recovering cached files. Background technique [0002] The memory recycling mechanism of the Linux kernel is to reclaim memory according to the LRU (least recently used) rule when the memory is tight. If the file cache is reclaimed, it needs to be re-read from the external storage when it is accessed next time. This process will consume a lot of time. , especially when the electronic device has been used for a long time and the external memory is severely fragmented, the performance of re-reading is lower. [0003] The current technical implementation is to recycle the least recently used pages in the system. In fact, there are some defects. It is very likely that some file caches have just been recycled, and they need to be accessed again soon. At this time, IO operations need to be performed ag...
