Moving Install to Linux

Is there an easy way to transfer all of my game files to Ubuntu from Windows 7? I have Guild Wars on Steam; is it as easy as copying and pasting, or will I run into problems because of Ubuntu's file structure? This will be my first time running Linux, so I'm not familiar with using Wine. Thanks.

Copy your data on Use pen drive/ usb hard disk, cd/dvd, then copy to ubuntu.

U dont have to use Wine or Cedega ... think the app ive installed is Linux Gaming or something like that, free and in the Ubuntu store (sorry im not near my lappy to double check on the name)
