Active archiving

I was wondering if there's a way to activly archive ever changing folders that I'd wish to keep after formatting my computer so I don't have to worry about such things as losing recent links in my favorites folder. Can this be done? I keep a partition as an archive that I carry over from reinstall to reinstall.
On a related note, to some of the less expireienced posters here... What I have decided is the best way to use a hard drive.
Partition as follows:
C: drive, 1500-2500 megs depending on tastes, but be sure to leave enough room for the swap file.
D: drive, 5-10 gigs dependant on tastes.The applications drive. Put all of your apps games, and anything else that makes registry modifications
E: drive. Rest of the drive, but I'd suggest at least half of the drive. Archiving. Place MP3s and movie files here. Anything read only.
When you feel your winders install getting sluggish give both the C: and D: drives the FDISK treatment after backing up game saves, and your favorites folder. Reinstall, and tweak to your hearts content. Then fill the apps drive once again.
Cheers and happy computering
