Management method of computer file system

Abstract

The invention relates to a management method of a computer file system. The method comprises the steps of determining a fragment sequence of a file according to a storage unit occupied by a file, calculating the dispersity of the file based on the fragment sequence, determining whether the file needs to be fragmented according to the dispersity, calculating the proportion of the length sum of thefile needing to be fragmented to the length sum of all the files, and determining whether to perform disk sorting according to the proportion.

Description

technical field [0001] The invention belongs to the field of computers, in particular to a method for managing computer file systems. Background technique [0002] A computer file system is a system for managing files on a computer disk, and the disk is usually organized in units of certain storage units, for example, in the form of sectors-tracks-clusters. A file usually occupies multiple storage units, and each occupied storage unit may be distributed in different places on the disk, resulting in physically discontinuous storage of the file. These scattered storage units are called file fragments. The more fragmented a file is, the slower it will be to read and write to that file. A large number of file fragments will slow down the read and write speed of the entire file system. [0003] In the prior art, for example, the Windows system provides the user with a disk defragmentation program, and the user can manually start the disk defragmentation program to defragment fi...

Problems solved by technology

However, most users will not actively start the disk defragmentation program. Even if the program is started, there are usually a lot of file fragments. Disk defragmentation is very time-consuming and the user experience is poor.
