Sorry it's only me - and I am only trying to help. Not being a "techie" myself either, I do not know the jargon "AOL". If it is America-on-Line then try asking them.
Although I don't exactly know what you mean by "personal filing cabinets" (I am not an"AOL" user) perhaps in your case that is what PFC stands for, (obviously not "Papermaster Filing Cabinet" in your case).
I assumed that, if you know enough about the merits of cleaning up your files, you would know how to use the Xp "Search for Files and Folders" by clicking "Help and Support". Perhaps you have not tried that yet. From the sketchy info that you have given so far it is not possible for me to try to help you further, nor, it seems, many other "AB" forum users .
