Greetings, Matt D.!
> On Windows you can create symbolic links which point to volume UUIDs as

> C:\
> ...
> mklink /d test \\?\Volume{079b79c9-0000-0000-0000-100000000000}\
> ...
> dir test
> I call mounvol to get a list of volumes and create a symbolic link
> 'test' which points to the C:\ UUID. When I then 'dir test' it will list
> all files on that volume.
> If I try to access it through Cygwin Bash I get the following error:
> $ dir test/
> dir: cannot access 'test/': No such file or directory
> This makes it difficult to work with unmounted volumes as it's not
> always possible to access the administrative disk management snap-in and
> the mountvol/mklink has always been my go-to for this type of
> functionality. It would be great if Cygwin would support it.
