Claudiu,
you asked this question first at 06:37 (Pacific time); at 10:34 you say that you don't have time to read the manual and it's an emergency. In the four hours between your two posts you could have read the whole manual twice.
The part about copying files to the zip disk is half a page, if I remember correctly.
Do you know what I mean?
