Abstract: A method for software update management is described. The method comprises: comparing sub-files of a plurality of variants of a software program to generate difference information including a list of uncommon sub-files among the plurality of variants; generating one or more increment files based on the difference information and files of a target version of the software program; and transmitting the one or more increment files to a device, wherein the transmission enables the device to merge the one or more increment files with files of one of the plurality of variants to generate files of the target version of the software program.

Abstract: Disclosed is a method and an apparatus for incremental upgrade. When a server generates an incremental file, it acquires sub-files of different types in an old version compressed file and a new version compressed file, and performs different difference comparison steps on the sub-files of different types, to obtain difference data files for corresponding types: for sub-files that satisfy a preset decompression condition, a decompression comparison method is used to perform difference comparison, and for sub-files that do not satisfy the preset decompression condition, a direct comparison method is used to perform difference comparison; subsequently, a client acquires the difference data files from the server, and according to the type of a difference data file, carries out a merge operation on the difference data file and the old version compressed file to obtain the new version compressed file.
