Patch Maker

About this app

Need to create small and efficient updates/patches to your program? The life of a software product is usually marked by the release of different versions. One version differs from the previous one by a small number of changes. Some sections of code in the executable files are different, new files may be added, some even deleted. What the author of the product usually does is provide a whole new version of the files either as a new reinstallable product or just the modified files, compressed into an installer. The above procedure is very wasteful though. For example, if a file of 1 megabyte has only had say 10 kilobytes altered inside it, then why create an update patch that requires the full 1 megabyte? It would be far more efficient if just the altered data was stored. This is the purpose of Patch Maker, as it saves a huge amount of bytes by storing just the differences between files and even compressing this data.
