Is whitespace name possible? I tried:

os.mkdir(r'C:\somedir\ ')

and it gives the error:
WindowsError: [Error 183] Cannot create a file when that file already 
exists: 'C:\\somedir\\ '

Every single way I can think of to try to make a name with purely space 
failed. Why not make os modules special case single whitespace folder? 
(give better reason than to quote the Zen)

anyway, you could always use r'C:\DataFileTypes\ '[:-1]
