Where are the mail files stored in Netscape 6.2

[Alex]

I need to migrate from Netscape 4.7 to 6.2 because I bought a new PC.  I
heard I can just copy my inbox file and the snm file, renaming extension
from snm to msf.  I installed 6.2 on my new PC, but I cannot find the folder
where these mail files are stored.  Can someone tell me where they are and
if my migration strategy will work?

Thx in advance.
