File reading method

Abstract

A file reading method is used for reading files of hard disks. The files correspond to a plurality of physical blocks in hard disks. The file reading method comprises detecting file system types of hard disks; reading address information of the files according to the file system types; obtaining a plurality of physical block addresses corresponding to the physical blocks according to the address information; sequencing the physical block addresses to obtain a physical address table, wherein the physical block addresses in the physical address table are arranged in an increasing or decreasing sequence; and reading the physical blocks of the files through a first reading means according to the physical address table.

Description

technical field [0001] The invention relates to a file reading method, in particular to a file reading method capable of increasing the reading rate. Background technique [0002] With the popularization of computers and the rapid development of network technology, the technology of hard disks has also developed accordingly. A general hard disk has at least one disk (disk) to store a large number of files, and the hard disk can read all over the disk by moving a read write arm (read write arm) and a read write head (read write head) with mechanical action. The data. Various file systems (file systems) are often used in the hard disk to manage a large number of files stored in the hard disk. For example, a file system can divide multiple tracks (tracks) of a disk into multiple sectors (sectors), and read and write data in units of sectors. [0003] When reading a file, it is necessary to determine all the logical block addresses of the file in sequence, and map the logical...
