They all should work. (They do on my machine when subtituting F with a drive letter that
exists here. Win 7, Python 3.4.2).

It's something else on your end that is causing the error. Is drive F: full? Do you have
the correct permissions? Is it a network share that has certain restrictions?
What exact python is is that you are running?
