It uses the "default drive" + "current directory on that drive".
If you say `open("c:spam")`, Windows uses "drive C" + "current
directory on drive C".
If you say `open("/spam")`, Windows uses "default drive" + "explicit directory".
Hence there are 26 current directories (one per drive), plus the
selection of current drive, which effectively chooses your current
directory.
