That kind of thing is not supposed to happen, Rendo is supposed to test that before it gets released to market I believe. I can understand if I move something that has a full path specified in a file, then I'm asking for it... but things like texture files, geometry, and deltas should not be moved. but rather saved into their proper directories when making a zip file to upload. Dumping everything into one file for a user to figure out is no help either as you still have to go through a bloody deep search for each item you load, or else give your text editor a workout.  I understand some people have no clue what goes where, and want to share stuff, but there are a lot of people who have used Daz/Poser for long enough that they should know better..that's just sloppiness.
Sorry...that's my pet peeve...rant over.

I've never known Poser to crash when this happens but I rarely use it.
