Linda,
I do not know what you mean USE that file.
I can import that .PST file onto any computer I want to if I have Outlook on it and want to import additional CONTACTS or whatever.
I have done it already. Several times.
But , the topic was backup. If you re-install your operating system and MS Office wnd want to use the OUTLOOK program and put all your contacts (address book) in there, as well as your inbox email all you have to do is open Outlook and IMPORT the appropriate .PST file you exported.
Works like a charm.....
Did I answer your question or did I miss it completely? Not sure......
the best,
