Remove Old Mediabay Databases?

I would like to reset my media and remove all old databases to audio files. I move a bunch of folders around and have done rescans and refreshes of the entire system but I keep getting these ‘ghost’ files that reference an old location.

Is there a pref or file I can trash to remove these old references and just start from scratch?

Thanks in advance!

Look to the Prefs Files link in my sig.

Perfect, thank you, this worked, I deleted my mediabay3.db, mediadefaults.xml, and fileobserver.xml files and it cleared my mediabay db.

Thank you again.
