I need to find my notes on this topic as I vaguely remember that fixing it would introduce inconsistencies. No objection to changing WindowsFileStore.create to check for ERROR_INVALID_PARAMETER but I'm not immediately confident that there are other issues lurking. The real we didn't add support originally is that we assumed that it was a legacy mechanism from DOS days.

Yes, the main problem we had was [1]. I have a patch that appears to fix this, but I don’t think that all ramifications have been considered and there is not a sufficient test as of now.
