What is a PFC file? A PFC file is a personal filing cabinet created by AOL Desktop Software, an application that lets America Online (AOL) users access their AOL accounts. It contains an address book, a record of bookmarks , stored email messages, away messages, and newsgroup postings. Each AOL Desktop user account has an associated PFC file.

More Information AOL Desktop is a software application that AOL users can use to browse the Internet, send instant messages, and access their accounts. The program stores account-specific information, such as a user's favorites and sent and received emails, in a user-specific PFC file. PFC files are compressed binary files. You cannot simply open a PFC file to view your email messages or favorites outside of AOL Desktop. However, a variety of third-party programs and utilities allow you to extract various pieces of information from your PFC file, if necessary.
