Example Embodiment

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, wherein the exemplary embodiments and descriptions are only used to explain the present invention, but are not intended to limit the present invention.

[0030] see attached figure 1 , which shows the basic flow chart of the method of the present invention. Based on this flow chart, the steps of the present invention are described in detail below:

[0031] Step 100: Continuously number each storage unit on the disk according to the sequence of continuous reading of the disk.

[0032] Generally speaking, in a file system, each storage unit of a disk has been numbered, typically a disk cluster number. The numbers are in the order in which the disks can be read and written consecutively, that is, the physically consecutive storage units are consecutively numbered. Numbering can start from 1, that is, the first storage unit is numbered 1, the seco...

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...
