Actually, the opposite is true, at least for 3rd-party (non-Microsoft) archiving tools: they work even when there's a whole .exe file stuck on the front. ;-) Some of them require you to rename from .exe to .zip first, but some actually detect that an .exe is a stub in front of a zip file and give you extraction options in an Explorer right-click. So, no worries on the prepended data front, even if the extension is .zip. What you probably can't safely do is *modify* a .zip with prepended data... and there I'm just guessing, because I've never actually tried.
