I can see what's happening now

TSD is sorting folders, devices & drives, and network locations by their
names. I don't think there is a parallel to this drive sorting scheme in Windows Explorer.
I've only noticed this recently because my drives were all the same until one died and I replaced it with a different brand which has a different name. So now that new drive appears in a different position in the list!
I could give them new names to force a their sorting order, but I'd much prefer it if the drives were sorted by their drive letter. The reason for that is that I want to name the drives with the broadcasters' call-signs and that is going to make them appear in many different places in the list in TSD.
