Windows Vista Personal Address Book location?

I am trying to locate the personal address book file that is used by Outlook, but can't seem to locate it. I know it is a separate file from the "contacts" that Outlook shows. I need to do a clean install, but have three profiles on this computer with separate address books. I can't afford to lose them. Anyone have suggestions? I've already tried searching the computer for *.pab and have had no luck. Does Vista store them differently?

Thanks,
Shannon

 

In modern Outlook versions all data is stored in PST files, including contacts.
