Client end incremental updating method and system

Abstract

The invention discloses a client end incremental updating method. The method comprises the steps that A, a server generates incremental patches by comparing all files of a new edition client end program and an old edition client end program, a file updating list is established, the incremental patches and the file updating list are stored in a file folder which is named by a current version number, and the current version number of the server is progressively increased; B, the client end downloads the file updating list according to the current version number, the file updating list is compared with a local file list, and a downloading list is generated; C, the client end reads the downloading list, and needed patch files are downloaded; D, if the downloaded patch files are difference package files, the increments of the patch files are updated into a local old package file; otherwise, the patch files are used for replacing local same name files; E, after downloading and updating are completed, the md5 value of the local file is calculated again and is stored in the local file list, and the current version number is modified. The invention further discloses a client end incremental updating system.

Description

technical field [0001] The present application relates to the technical field of computer networks, and in particular to a method and system for client incremental update. Background technique [0002] With the development of online game technology, the size of the client terminal is also getting larger and larger. Frequent and rapid update of game content is a characteristic of online games. Usually resource files occupy a large part of the total size of the client, and resource files are often organized according to a certain classification method, merging similar files into a package file, and then encrypting and compressing. This not only ensures file security, but also effectively reduces the size of the client. A package file is a special file with an internal file system. The package file has its own directory structure inside. The package file is often used to compress and encrypt files with similar functions or a certain category. It is convenient for management, ...

Problems solved by technology

[0006] Among them, the disadvantage of method 1 is obvious. When the file to be modified changes very little and the file itself is very large, you have to re-download a very large file for a small modification, which takes up a lot of bandwidth.

The problem with the second method is that if the file is encrypted or compressed, the binary difference cannot be extracted accurately.
