Duplicate Downloads in Vista

How can I stop downloads from going into more than one file in MY COMPUTER? In my list of files in My Computer I have: desktop,Bon & Don, Drive C: ect.
Under Drive C:/Users I have two separate files; one is Don and the other is Len. Everytime I download my pics from my camera or other data from the internet the downloaded files go into the Bon & Don,and also Don and Len files. I just want to keep the Bon & Don File, but when I try to delete the individual Don & Len files it also deletes whatever is in the Bon & Don File. How can delete the duplicated files in the Don and Len files without deleting the same files in the Bon & Don file? Any help will be appreciated. Thanks.
