Ubuntu 7.04 Files: Find, use USB

I want to move my Halo files from my NTFS volume to a USB drive (2 GB Attache). Where are they? I figured it out, but I have to set up Desktop Search to index all the volumes -- right now it's just /usr. No wonder it doesn't find anything. So, I found the folder the old fashioned way and copied it to the USB drive, which mounted no problem, and also ejected without a hitch. That's cool.
