Abstract: The present invention provides an incremental upgrade method, an apparatus applying the method and a storage medium. The incremental upgrade method comprises: sending a request to a server for downloading an incremental upgrade package corresponding to a local old version file on a terminal; receiving the incremental upgrade package, which comprises unmatched block data obtained by comparing a first compressed file with a second compressed file, and the start and end information of the unmatched block data, wherein the first compressed file is a compressed file that concatenates an old version file and a new version file on the server, and the second compressed file is a compressed file of the old version file on the server; concatenating the unmatched block data in the incremental upgrade package and a local second compressed file generated from the local old version file on the terminal to generate a concatenate compressed file; and at last decompressing the concatenate compressed file to obtain the new version file. The method reduces data traffic and occupied bandwidth resources.
