**XENA Please Help**

Ok so I have CDmage. I also have the Spiderman .CDI file which is to big for my CD. So I open up the image but what files should I delete? and how do I go about deleting them. The CD I'm using is 700mb and the game is 735mb. So I need to take off about 35mb.

Any help would be really really nice
Thanx
