ActivePatch

ActivePatch is a software development toolkit that enables developers to create their own updates in the form of a patch, and integrate the patch application process directly into their own software. Unlike other products, ActivePatch analyzes each file at the byte level, and determines the best method for updating the target file on the user's system. ActivePatch is designed to work on both text and binary files of any type, including executables, libraries, data files and documents. It can be used to create a patch of a single file, or can be used to create an update for a complete product, modifying existing files, removing files that are no longer needed and creating the new files that have been added.
