Is this HostFS on VirtualAcorn? In which case all bets are off - it depends
on how VA implements things, and whatever Windows behaviour it depends on.
I wouldn't be surprised if there's some nuance of the filing system API that
it doesn't support correctly, or isn't specified well enough.

You could try on a virtual ADFS disc inside VA to see if it agrees.
