Petite - Version 2.2 Executable compressor - the compressed files can be executed just like before they were compressed. What sets Petite apart is that it can compress all parts of the executable - code, data and resources. As executables can have a lot of empty data, this results in a great reduction to the size of most executables. Petite automatically determines which parts of an executable are compressable and which parts need to be kept as they are.
