You don't "copy" files to a CD - you burn them using some sort of burning
software - e.g. Nero or whatever burning software came with your burner.

What Bill said.

The upshot is, unless you have something installed like Direct CD, you can't
just copy files to a CD and use it like a harddrive. You have to use some
type of software utility to burn the files to the CD. Windows XP will do it,
so will software from places like Roxio and Nero (can't remember the Nero
mfg's name, right now...oh, maybe Ahead software or something like that?).
