I agree with David - 2 things to add to what he said. Before deleting unused audio, delete any unused and unneccessary playlists. Second, in the audio regions bin use "Show Full Pathnames". Examine this to be sure you are nuking the correct files. Once you wrap your brain around this delete files thing, plus the "disk allocation" concepts, it's not all that difficult. Procede with caution!!!
