Abstract

The invention discloses a defragmentation method, a terminal device and a computer readable storage medium. The method comprises following steps: obtaining a first file parameter and a second file parameter; the first file parameter is used for describing the fragmentation degree of a file and the second file parameter is used for describing the frequency of the file being operated; determining the defragmentation assessment parameter of the file according to the first file parameter and the second file parameter; when the defragmentation assessment parameter is larger than a preset threshold value, performing disk defragmentation on the file. The invention provides a defragmentation method, a terminal device and a computer readable storage medium. The fragmentation degree of a file is assessed through combining frequency of the file being accessed and the frequency of the file being corrected so as to determine whether to perform defragmentation; combined with scattered fragmented sections, gathering parts into a whole, carrying the fragmented sections to another continuous block of the same block group so as to avoid the amount incensement of bad sectors and prolong storage service life.

Description

technical field [0001] The invention relates to defragmentation technology, in particular to a defragmentation method, a terminal device and a computer-readable storage medium. Background technique [0002] On current mainstream Android phones, the data partition and the built-in sdcard partition have been merged, and the ext4 log file system is still used at the bottom layer. The ext4 file system considers the fragmentation problem at the beginning of its design, and adopts corresponding coping strategies, such as multi-block allocator, delayed allocation, block groups, etc. But when files continue to increase, or storage space starts to fill up (%85), fragmentation may still occur. Especially in the Android system, with the use of the app, the app data continues to expand, the storage space becomes more and more tight, and file system fragmentation is inevitable. This in turn leads to a decrease in system IO performance, and even affects system fluency and user experienc...
