windows 10 – With psubst version 3 what is the proper syntax when the path contains one or more blanks?

Obviously there are two separate issues: The syntax must be accepted by psubst version 3. Alas, just because that works doesn’t mean that the new virtual drive will actually work. Let’s assume that you have a directory named c:one blank
and you want to define virtual drive t: to be that directory. So what needs to
be added to

                   psubst t: c:one blank 

to make it work?
