Most compression programs compress all files by default. But when archiving a folder containing already compressed files, there is no need to compress them a second time, such as archives, packed setup program, jpg, movies, mp3,....
Are there any compression programs that allow an arbitrary list of type of files to be stored while the others are still compressed ?
It looks like Winrar can't.
I expect this would be doable with tar+gz/bzip2 and some scripting in various ways.
