Embodiment Construction

[0093] A method and device for processing a FAT image file provided by the present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.

[0094] Such as figure 1 As shown, the embodiment of the present invention provides a kind of method of FAT image file processing, and its specific implementation mode is as follows:

[0095] Step 110: Create a compressed file of the FAT image file.

[0096] In this step, an empty compressed file is created.

[0097] Step 120: Add the structure information of the FAT image file and the data of each used data structure of the FAT image file to the compressed file, and the compressed file does not include the data of the unused data structure in the FAT image file.

[0098] The data structure of the FAT image file is a component of the FAT image file, that is, a component of the corresponding FAT file system. Taking the FAT16 / 32 file system as an example, it can be divided into the o...

Abstract

Embodiments of the invention disclose an FAT mirror image file processing method and apparatus. The method comprises the steps of creating a compressed file of an FAT mirror image file of a file configuration table; and adding structure information of the FAT mirror image file and data of each used data structure of the FAT mirror image file to the compressed file, wherein the compressed file does not comprise data of unused data structures in the FAT mirror image file. The compressed file does not comprise the data of the unused data structures, so that the size of the compressed file is reduced. In the way, storage resources occupied by the compressed file of the FAT mirror image file are reduced, and the required transmission time of the compressed file under the same transmission speed is shortened, so that the transmission efficiency is improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for processing FAT image files. Background technique [0002] File Allocation Table (Fill Allocation Table, FAT) file is a common file system type, the existing FAT type file systems are FAT16, FAT32 and EXFAT file systems, commonly used in hot-swappable removable storage such as U disk On the device, both the Windows system and the Linux system can support these FAT file systems. [0003] The current FAT image file stores the complete data structure of the FAT file system, which will cause a series of problems. For example, in the process of transferring the image file of the FAT file system, it is often limited by the transmission medium, such as the limitation of network bandwidth and USB speed, and the transmission efficiency is low. As another example, for the storage of the image file of the FAT file system, there is also a problem of occupying too many storag...
