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.
