Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] The existing solution is that the two FAT tables are the same, and the seek must start from the beginning of the file. The present invention aims to improve the seek to realize fast and efficient file seek.

[0035] In the FAT standard, the purpose of defining two identical FAT tables is for backup to ensure safety. The reason for this is to ensure the safety of the FAT table. Once the first FAT table is damaged, it can be repaired with the second FAT table. The actual situation shows that the second FAT table usually has little meaning, and the FAT itself has no power-off protection mechanism, so once the power is cut off physically, even saving two FAT tables will not help. Therefore, the present invention redefines the second FAT table, r...

Abstract

The invention provides a method and system structure of using file allocation tables to make file section routing. And the system structure comprises first and second file allocation tables, and it sets the item value stored in each item in the second allocation table as an indexing value for the previous item so that the two file allocation tables form a two-way link list, and uses the two-way link list to make file section routing. And it implements a two-way link list structure in the file allocation tables, reduces the time for file section routing and lays solid foundations for smooth multimedia playing.

Description

technical field [0001] The invention relates to the disk management technology of a computer, in particular to a method and system architecture for file seeking by using a file allocation table. Background technique [0002] FAT (file allocation table, file allocation table) is a file system defined by Microsoft to manage disk data space. It was created in the late 1970s and early 1980s. It was originally used in the MS-DOS operating system. FAT was originally designed to position it as A simple file system is only suitable for floppy disk management, and the floppy disk at that time had a storage range of only 1M. With the continuous development of new technologies, the disk storage space is constantly increasing, and the original FAT design can no longer be satisfied. Therefore, Microsoft has expanded FAT on the basis of the original, that is, the three file systems we commonly see now, FAT12, FAT16, and FAT32. It has basically satisfied the space management of different ...
