what
FOBSIDE said: what program are you using? also, what OS? (since i know there are differences between the OS, esp for mozilla and some others)... from your rig, it seems like you are using win98SE, but just in case ........
just to add to the list:
netscape 4.7x (and below) stores the emails in
c:\program files\netscape\users\your_username\Mail. copy all the files there and dump them when you have done reinstalling netscape
mozilla / netscape 6.x:
c:\documents and settings\your_w2k_login\application data\mozilla\profiles\your_profile_name\some_random_mozilla_thing\Mail (win2k -- don't remember the directory in win98). as above, just copy the mail directory, then dump it back when you're done installing...
your second question, what else to archive?
well, if you are using mozilla/netscape, it's easier to backup all the user directory (which includes mail, bookmark, etc), and dump them back when you're installing them again .... this is so you can later on import your settings easily.....
other than that, your favorites (C:\Documents and Settings\win2k_login\Favorites on win2k, or C:\Windows\Favorites on win98) ... don't want to miss all the pr0n bookmarks now, do we?
also, you may want to backup the directory where you install your instant messaging softwares (if any)
and your files and settings for your distributed computing softwares, if any ....
and your save games, or patches for the games that you have downloaded ... and also include the browser or some add-on softwares (esp if you spent your time on 56k downloading these mess like i did)
and last but not least, all the moviez, mp3, pr0n, and some "interesting pictures" that you have

.... (yes, i admit i have those too
