Abstract

The invention provides a file processing method and device applied to terminal equipment and a server. The file processing method applied to the terminal equipment includes the steps that a first version of a first file is partitioned in a file system layer, so that a first number of file blocks are obtained; write operation performed on the first file on the basis of the first version of the first file is received; corresponding to the write operation of the first file, a second number of new file blocks are generated; for all the new file blocks, the file blocks, corresponding to the new file blocks, in the first number of file blocks are determined, and difference blocks of the new file blocks and the corresponding file blocks are generated; storage operation performed on the first file is received; corresponding to the storage operation, a second version of the first file and the different blocks are stored, wherein the second version of the first file includes the result of 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 ...
