Embodiment Construction

[0084] In order to make the above objects, features and advantages of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0085] The invention provides an electronic device and a file segmentation method applied to the electronic device,

[0086] see figure 1 As shown, it is a flow chart of Embodiment 1 of the file block method of the present invention, the method is applied to an electronic device, and the method includes:

[0087] Step 101: Receive a file modification operation.

[0088] After opening an existing file or creating a new file, the user can modify the file. Specifically, the modification of the file can include inserting, deleting, and replacing while deleting and inserting. As a device directly operated by the user, the electronic device can monitor and receive file modification operations in real time...

Abstract

The invention discloses electronic equipment, and a file partitioning method applied to the same. The method is applied to the electronic equipment, and comprises the following steps of receiving a file modification operation; obtaining a file partitioning range corresponding to the file modification operation according to the file modification operation and a first partitioning result; obtaining a first file partitioning instruction; carrying out a first partitioning operation on data in the file partitioning range according to the first file partitioning instruction to generate a second partitioning result; when obtaining a file synchronization instruction, transmitting the changed file block according to the second partitioning result. By utilizing a partitioning history result, after a file is modified, the file partitioning range corresponding to the file modification operation can be obtained, and only the data in the file portioning range is re-partitioned, so that the file partitioning time is shortened, the file partitioning efficiency is improved, and the amount of data transmitted when the file is synchronized is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an electronic device and a file block method applied to the electronic device. Background technique [0002] Duplicate data transmission may occur during the interaction between the mobile device and the cloud server, which greatly reduces the efficiency of data synchronization. For example: the user may only change a few bytes in a file, if the synchronization algorithm still completely uploads the entire file to the cloud server, it will cause unnecessary traffic overhead and time overhead. Therefore, it is necessary to perform file synchronization by uploading only the difference part of the file. [0003] The current difference algorithms all need to divide the entire file into blocks in advance, and in the prior art, a variable-length segmentation method based on content blocks is generally used. However, this method needs to scan the entire file to complete file se...
