I want to try something I've never done before, which is backing up some
files by writing them to a CD. One of the files is the OE address book.
Using the Search feature, I typed the keyword "Address" and got 11 hits, of
which six were labeled as shortcuts. Double-clicking most of these shortcuts
opened up the familiar address book window. However, if someone can help, I
don't know which is the actual file that I want to back up.

Windows XP.
