Don't know if you will see this reply, now more than 2 years later.
PFC files can be opened and read using AOL Desktop software, not the new version called AOL Gold.
If you can get an installation copy of AOL Desktop - I think the latest version was 9.8.2 before AOL discontinued it circa October 2017 - and install it on your computer, then you should be able to open and read the PFC files entirely within your own computer - no need to be logged on or even be a current subscriber to AOL. Just click on the File menu, then Open and navigate to and select the file.
AOL Desktop was always free. You might be able to get it somehow from AOL, phone 800 827 6364, or, if not, do some googling for AOL Desktop.
