So THAT is where it went!!!!

Anyone know anything about the program "Express Scribe"? I'm using it to transcribe a bunch of interviews for the Secret City documentary, but I've just discovered that over 2 of my 3 gigs of hard drive space that I cleared up so that I could copy over all of Amanda's wedding pictures has been stolen away by old audio files - apparently, once I click "Done," it archives the audio files to some hidden and unknown spot on my hard drive where they cannot be deleted. I think it automatically deletes things after 30 days, (I changed that pref to 1 day), but if I can clear them out sooner, it would be great. Maybe I need to check the "help" section in the program. That would probably be a good idea.
