recovering email files not in archived .pst format

What are the file extension names or a directory location for msn email messages?

My old hard-drive (was using Win 98) is now a slave drive on my new PC (running XP). The upgrade was a rush request and I did not use the export feature in MSN email before switching. I reinstalled MSN on the new set up, but would like to retrieve old email from wherever it is stored on the slave drive.

Is this doable?

Thx much!

 

No luck with *.msnbak Any other extensions used?

btw, thanks for your help!
