I am reinstalling windows for a friend. He has a large number of emails saved on his computer downloaded through MSN6. These emails are not reachable through webmail and he wants to keep them. I assume they're in some kind of database file. Where is this file located, and how can I back it up in a way that it will be accessible by the new version of MSN that I download.
Sorry for the basic questions but I learned how to use computers on Mac OS and linux so I'm not much of a Windows power user.
