    To keep Fitness and its settings on an external drive (in Windows):
        First copy the program folder, e.g. C:\Program Files (x86)\Fitness\
        Then, either copy your local settings folder, e.g. C:\Users\Me\.fitness3
             (Windows XP: C:\Documents and Settings\Me\.fitness3)
        into your new copy of the Fitness\ program folder,
        or make a new folder called ".fitness3" inside your new copy of the program folder.
