Windows 7 Why do I have multiple "My Documents' folders in user window?

[tape]

When I click on my personal folder icon on right side of start menu, I see a listing of all that is located in my C:/Users/Personal folder, PLUS 4 additional My Documents folders. I have my HD partitioned so my documents are on D: One of the 'My Doc' folders refers to the empty folder on my C:, and then I have 4 more that all are linked to the actual documents folder on my D: Deleting the extra 3 doesn't help in that when I tried that I found I actually deleted all my documents (TG for backups). All the D: document folders have identical sizes, the same dates & contents. Because the document folder is 75 gig big, I can't just place one in the trash to see what happens. How do I get rid of all that I don't want to see in my personal folder? BTW--this is on a new laptop running Win7pro
