From <https://docs.python.org/3.7/library/os.html#os.rename>: > On Windows, if dst already exists, OSError will be raised even if > it is a file. ... > If you want cross-platform overwriting of the destination, use > replace(). Thanks to kerry liu (https://github.com/hqzxjczx) for reporting this. Fixes #32.
