How can I get Mathematica to stop creating the "Wolfram Mathematica" folder

When I startup Mathematica, it creates a folder in the My Documents folder on my Windows machine titled “Wolfram Mathematica”. I want it to stop doing that. On the other hand, if it must create a folder on startup, how can get it to create that folder in a different location outside of the My Documents folder? Thanks.
