subst x: myFolder
Works as expected. Maps a new drive 'X' to the files of "myFolder".
subst d: myFolder
Invalid argument - D:
Why is that?
Does this mean, that it is not possible to map do D:\ ?
subst (without parameters) prints nothing (or only X: if mapped).
So D is not subst already.
Any clues about that?
Oh dear lord, I feel extremely stupid now.
The Laptop I am working on has mapped the DVD drive (which is deactivated but still mapped, hence you can not see it in the explorer) to D:\
