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.
Advantages of using Patch Maker:
• Very small update patches, independent of the size and number of files of the original installation
• As most of the data is not stored in the update patch, it is impossible to steal your software unless you already possess a previous versions of the software
Patch Maker is the complementary product of the Clickteam Install Creator series. They share the same intuitive, professional-looking interface and they are equally simple to use. If you have used Install Creator you will feel right at home with Patch Maker.
