Virtual hard drives

[Tolis]

MC cannot see hard drives created from http://www.ntwind.com/software/utilities/visual-subst.html

I don't know what that tool does.
But MC only ask Windows for all devices, and if the device is assigned a drive letter it should show up.
I don't see any reason for them no to show up if they are drive letters.
If it is only that they are not showing up if you assign them while MC is running then you can try refresh device in the device dropdown.

Visual-subst uses the internal subst CLI command of the OS, well known since DOS days:
https://en.wikipedia.org/wiki/SUBST
e.g.
subst w: c:\windows
will create a drive W:
(subst w: /D will delete the substitution)

From my tests in W10 64bit I can tell that MC is able to show this substituted drive letter without problems, when cmd.exe and MC are running under the same user. If one of these is running with admin rights and the other one not, then they will normally not share the drive letters. You could get around this behaviour with a registry key called EnableLinkedConnections = 1 but unfortunately with a recent patch this does not work anymore. Maybe Microsoft will fix this in next time. See more details here:
