Nonsense. You can mount filesystems to mount points in much the same way as is done in Unix. No one would ever need to do that.

[Dwedit]

You can indeed use mount points like C:\mountdir, but that's still on the C drive, which is a drive letter. It's not "no drive letters".

And if \ was an alias for C:\ this would just be \mountdir.
