Changing folder icons to show open or closed and changing default folder icons like "Favorites".

I have recentely learned how to change a folder icon manually in Windows Explorer, and now would like to be able to manually change the folder so it shows the folder open and shows the folder closed.

I would also like to know how to change default folder like "Favorites" and "Control Panel"

This little program seems to do it all.
