[Wine] Running games installed in Windows

[Pseudo_Bob]

So I have Guild Wars and World of Warcraft installed and running on Windows on my computer.  I just got Wine (and Ubuntu, for that matter,) running on the computer, and I was hoping there was a way to access the files in windows so I wouldn't have to take up twice the disk space on my hard drive.  Can anyone tell me how to do this (if it's possible)?
