Sure, but then the file name doesn't have any backslashes.
I've never understood why binary mode is supposed to be bad. By my
understanding, binary mode simply means that no line endings are
translated, regardless of whether the file uses \n, \r or a combination of
the two. Surely the worst that can happen in binary mode is that your
strings end up having some carriage returns you have to deal with yourself?
