It's not data corruption within the zip (or because of the zip), but because of any number of other reasons.  I've been bitten by this on several occasions - either a very old CD/DVD which has gone bad or bad reads/writes (and I always did verification).  Stuff happens and zip files are no less susceptible to storage corruption than any other file - just that it will take more of them with it.  If you have ten thousand Poser files in a zip and there is one error - all gone.  If you have them as individual files, one error may affect one or several files, but not all of them.  You've been warned. :)

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
