File system and file management method using the file system

Abstract

The invention provides a file system and a file management method employing the same. The file system comprises a file index table, F file attribute tables, a release cluster set link table and a release cluster set index table; the file index table is suitable for indicating whether all of the file attribute tables can be distributed or not; the file attribute tables comprise a file information table and a cluster set stream list; the file information table is suitable for storing relevant information of files; the cluster set stream list is suitable for storing start clusters of all cluster sets occupied by the files and the sizes of all of the cluster sets occupied by the files; the release cluster set link table comprises P link table units; each link table unit is suitable for storing a start cluster and the size of a current release cluster set, the position of a former release cluster set, and the position of the next release cluster set; the release cluster set index table is suitable for indicating that all of the link table units can be distributed or not. The file system and the file management method using the file system are small in file management section when being applied to large-capacity recording occasions, and can ensure the data read-write bandwidth.

Description

technical field [0001] The invention relates to the technical field of computer file management, in particular to a file system and a file management method using the file system. Background technique [0002] A file system is a file management method and data structure used by an operating system to specify a storage device or partition, that is, a method for organizing files on a storage device. From a system point of view, a file system is a system that organizes and allocates the space of a file storage device, is responsible for file storage, and protects and retrieves stored files. Specifically, it is responsible for creating files for users, storing, reading, modifying, and dumping files, controlling file access, and deleting files when users no longer use them. [0003] Traditional file systems (such as FAT file system and NTFS file system) are often used in general storage devices (such as disks), and these file systems have the advantages of complete systems and g...
