You can open a file with the extension .PFC - that is a formerly stored folder - or you can select a PFC (an Organizer File) from an AOL installation, which has no extension - the filename is the pure screenname.
 

The program now shows the lines of the file in a new window.
You can ...

• open and close folders by mouse, Space or Enter,
• see the contents of a line in a further window by a doubleclick with the mouse on the text part of the line, or by pressing Space or Enter,
• select an unselected line for export by a doubleclick on the icon or use F5,
• unselect a selected line by a doubleclick on the icon or use F6,
• highlight multiple lines with SHIFT + (mouse or cursor),
• toggle the highlight of a line with CTRL + mouse,
• start the export with a button, a menu item or F2,
• unselect all lines for export with SHIFT + F6 (e.g. after the export is done).

With the right mouse button you get a shortcut menu to mark lines, to clear marks or to start exporting lines.

With a checkmark in a menu item you can choose to select or unselect a whole folder for export (if highlighted) with F5 and F6.

Each line is stored in the original file as two parts like other mail programs do this too:
The envelope has a fixed length and holds the contents of a line you can see in the first window after opening the file - plus some pointers for organisation. The longer part holds an internal header and the contents of the mail/posting (which is packed, when received with AOL 7.0 or higher).

You can see the contents of the folder part of the active line or the envelope in details by pressing F7 and the internal header plus the whole mail/posting with F8 in a readable form.
 

To select, how you want the export, there are some preferences:

• A delimiter string to use between each mail, posting, item, ...
• A checkbox, if you want to use this delimiter between mails.
• A checkbox, if and where you want to include headers from outside AOL or CS.
• A checkbox, if you want to export mails as HTML or as plain text.
• A checkbox, if you want to export each mail into a single file or all into one file.

• Where you want the header of a posting (off, on top or at the bottom).
• A selection, if you want to use the delimiter (from the mail choice) between postings.
• A checkbox, if you want to export postings as HTML or as plain text.
• A checkbox, if you want to export each posting into a single file or all into one file.

• Export with descriptions, as hyperlinks or as IE Favorites.
• A selection, if you want to use the delimiter (from the mail choice) between favorites.

• Export with descriptions or as LDIF (can be read by other programs).
• A selection, if you want to use the delimiter (from the mail choice) between these items.
• A checkbox, if you want to append "@aol.com" to addresses without an @ character.

In AOL 6.0 the addressbook has moved to a file with the suffix ABX - with mich more items. In AOL 7.0 and later the ABX changed to ABY, which holds encrypted data and cannot be read with this program yet.

• A checkbox, if you want to use the delimiter (from the mail choice) between the items. Here you can also select the language, the program shall use.

(These three topics are stored with descriptions)
 

All you select in these preferences as also the sizes and positions of the windows of this program and the folder, where the last file has been opened from are stored at one place in the registry to start next time with the same values you had, when you left the program.
