You didn't answert the question. What is the actual string you pass to
os.listdir after you got it from the user? You could
    print repr(fileroot)
to find out.

My tentative guess is that maybe Windows doesn't like newlines in file
names (I know UNIX allows them, but they're still usually a bad idea)
and maybe you string ends with a newline.
