Method, device and equipment for accessing files

Abstract

The invention discloses a method, a device and equipment for accessing files, and belongs to the field of computers. The method includes searching an extended data segment in a first index node according to a path name of a file; acquiring a second index node according to the extended data segment and the path name of the file; and acquiring the file corresponding to the path name of the file according to the second index node. The extended data segment is used for representing a hotspot item and an address corresponding to the hotspot item. The device comprises a search module, a first acquisition module and a second acquisition module. According to the technical scheme, the method, the device and the equipment have the advantages that the hotspot item and the address corresponding to the hotspot item are added into the extended data segment of the first index node, so that the index node acquisition speed can be increased, and the file access time can be shortened.

Description

technical field [0001] The invention relates to the computer field, in particular to a file access method, device and equipment. Background technique [0002] With the rapid development of computer technology, computers have become an indispensable part of people's work and life. When a user uses a computer to access a file, as long as the file name is found, the computer can find the physical address of the file through the file system according to the logical relationship of the information, and then the computer reads the file according to the physical address and displays the file to the user. As users frequently access files, access speed becomes an important evaluation index of computer performance. [0003] In the prior art, a computer saves specific topology information of a directory or a file through an index node, and permanently stores the index node on a storage medium. When a computer accesses a file, it searches the directory file for a directory entry that ...

AI Technical Summary

Problems solved by technology

[0005] The existing technology accesses files by searching the index nodes corresponding to the file path step by step. For the case where there are a large number of subdirectories and files in the directory file, but the actually accessed files are often concentrated in a certain part, each time the system is reloaded. It needs to be retrieved repeatedly on the storage medium, which increases the access time of files and reduces the efficiency of file search
