How are folders named in Windows Vista

I have redirected several of my folders in Vista as I have previously in XP
so I didn't have to change my document locations. However, many of the
references so the folder as My Documents while the Vista folder is just
called Documents. I am not able to change the location of these folders
even though I have successfully redirected all of the locations. How do I
complete these changes so my applications function normally?
