We don't currently have a way to get all the root directories on Windows, sinceos.listdir('/') doesn't contain everything.

I propose a very simple API:

>>> os.listdrives()["C:\\", "D:\\", ...]>>> os.listdrives(uuids=True)["\\?\Volume{4c1b02c1-d990-11dc-99ae-806e6f6e6963}\", ...]

Basically,listdrives(uuids=True) would return everything found byFindNextVolume, whilelistdrives() would applyGetVolumePathNamesForVolumeName to each GUID and return all of those. (This may return the same volume multiple times under different names, which is fine -os.stat can be used to see if they're the samest_dev.)

There's an endless amount of variations we could also apply here, but the most important functionality in my mind is to expose the OS API. App developers at least then have a starting point to do whatever they may need.
