Problems solved by technology

[0002] At present, there are many IM communication tools including client software and servers, such as QQ communication system. Among them, the system has a network disk function, which is to use the client software to upload files from the client to the server; because, in many cases, the files need to Frequent modification will upload the entire file to the server multiple times. If the file is not modified much, this transmission method has the following defects. First, it will slow down the upload speed, and second, it will take up space on the server.

Embodiment Construction

[0032] A system for transferring files provided in this specific embodiment includes a server for storing data and client software for installing on a client to realize the client logging into the server, and the client software includes:

[0033] A judging module, used to judge whether the file to be uploaded is a modified version of a file on the server before uploading the file to be uploaded;

[0034] Segmentation module, for when the file to be uploaded is a modified version of the certain file, the file to be uploaded is divided into M data segments from front to back according to the segmentation rule, M is a natural number greater than or equal to 1, The segmentation rule is: when the size of the file is less than *KB, *>0, then the file as a whole is a data segment; when the size of the file is T times of *KB, N is a positive integer, then the file is from It is evenly divided into T data segments with a size of *KB from the front to the back; when the size of the fil...

Abstract

The invention relates to a system for transferring files, which comprises client-side software and a server. The client-side software comprises a judgment module, a segmentation module, a comparison module and an uploading module. The files are saved in the server in a segmenting mode, the files to be uploaded are subjected to segmental analysis by the client-side software to confirm that the files to be uploaded are new data segments relative to the files in the server, and then the new data segments are uploaded so that the server can save the files to be uploaded. Therefore, the system for transferring the files can facilitate fast file uploading of the client-side software to the server and does not occupy the server space.

Description

【Technical field】 [0001] The invention relates to a system for transmitting files, in particular to a system including client software and a server communicating with the client software, and a method for uploading files between the client software and the server. 【Background technique】 [0002] At present, there are many IM communication tools including client software and servers, such as QQ communication system. Among them, the system has a network disk function, which is to use the client software to upload files from the client to the server; because, in many cases, the files need to Frequent modification will upload the entire file to the server multiple times. If the file is not modified much, this transmission method has the following defects. First, it will slow down the upload speed, and second, it will take up space on the server. 【Content of invention】 [0003] A technical problem to be solved by the present invention is to provide a system including client sof...
