Just doing a quick google search shows PFC files as proprietary AOL "Personal File Cabinet" for storing e-mails. Can you actually play the CD on your computer or CD player? If there are audio tracks on the CD they will be cda or mp3, wma, etc.
Did a little bit more digging about ProfusionDmx and this is the first I've heard of it. PFC or Perfect Fit Component seems to be exclusive to Profusion. You might be out of luck converting them, sorry.
