If you try to create a file or directory that already exists on Windows,
you'll get a WindowsError with error code 183:
>>> os.mkdir('C:\\common\\games')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
WindowsError: [Error 183] Cannot create a file when that file already
exists: 'C:\\common\\games'

I'm pretty sure you have to delete the existing file before you can
"overwrite" it. You can try to write the file and delete the file and
try again in an except OSError block (this will catch WindowsError as
well since it's a subclass of OSError, and it will catch similar errors
on other platforms).
