Hi,
If you defrag your drive once a week you can't really go wrong, I do mine once a week whether or not windows says too or not, depends on how much moving stuff around I do, installing and uninstalling stuff.
I never set windows to do it, I do it manually when I want.
As far as I know there is only 1 file that windows doesn't like moving, and that's the page/swap file as it is being used by windows.
Other then that, thread is a little confusing... :hehe:
