Hi Gary, Frankly, there aren't many, if any types of files that WinZip does not handle.
To date, I haven't found any, in any case. As my friend also said, it's good to have both, if only because some people prefer to have one zip utility over another, but, having said that, if you're going to create an archive to share with others, then it's best to make a zip archive, instead of any other, like RAR or any of the others that WinZip supports, only because some people can't afford other programs like WinZip 14 or WinRAR, so they opt to go with the native zip extractor that comes with Windows XP Vista or Windows 7, which, I'm told does not handle other file types very well. Just a note on this, in case you were thinking that one zipping utility compresses better than the other. Hope this helps.
