hmm, I know there is a MS article that is long and involved on using disk management to do it...but I think it just links them to another partition and doesn't actually move them. I always learned that desktop, settings, stuff like that was on the root drive with XP installed
And I think if you use the disk management method to move the stuff to the other partition you'd end up having to re-do it each time as the settings would be negated when you re-installed XP..you might just wanna back up stuff often hehe
For the 'my documents' folder: open Windows Explorer, right click on the my documents folder, select properties, 'target' tab... you can select where you want to store that folder from there.
To save a custom theme, set it up the way you want, right click on the desktop> properties> 'themes' tab, click the 'save as' function and save the your_theme.theme file in your 'my documents' folder. If you have a custom wallpaper and a hacked theme in place, you'll have put those things in place before this theme file will work for you.
Email storage folder. Open OE> Tools> Options> 'maintenance' tab. You can select a storage location from there.
I manually go into the 'Documents and Settings' folder, and to my user name and save my 'favorites' folder before i do a new installation.
