Winzip reads multiple formats. Most of which are used by other programs as well. If you break it down, there's not much to a compressed file; just a dictionary followed by the compressed data. I'd imagine that most compression programs are fairly compatible with other ones (unless they do something proprietary to the data like WinRAR does).
