Abstract

Provided are a file processing method and device used in terminal equipment and servers. A file processing method applied to a terminal device includes: dividing the first version of the first file into blocks at the file system layer to obtain a first number of file blocks; receiving the first version of the first file based on the a write operation to the first file; in response to a write operation to the first file, generating a second number of new file blocks; for each new file block, determining whether the new file block is within the first number of Corresponding file block in the file block, and generate a difference block between the new file block and the corresponding file block; receive a save operation for the first file; and in response to the save operation, save the first file a second version and the difference block, wherein the second version of the first file contains the operation result of the write operation.

Description

technical field

[0001] The present invention relates to file management, and more particularly to a file processing method and device capable of storing and transmitting files more effectively. Background technique

[0002] At present, a large number of network disks are emerging, such as Sina network disk, 360 network disk, Baidu network disk, Huawei network disk, etc., users can save their files on the network disk at a small cost, so that they can realize Access and sync files anywhere.

[0003] On the other hand, after modifying the file on the terminal device, the user needs to upload all the modified file to the network disk server, so as to replace the original file stored on the network disk with the modified file. When the terminal device is a terminal device that pays according to the network data flow, such as a mobile device or various terminal devices of an ADSL user charged by traffic, etc., uploading all the modified files to the network disk server may mean ...
