This is an annoyance more than a roadblock, but it doesn't seem to make sense.

On my XP box, I got used to subst or mapping drive A: to my general notes and work in progress folders, and drive B: was my current project's source code that I was working on. As these are historical drives that don't get used by a hardware device anymore, I felt safe using them.

Now on Win7 - I can subst or map either drive and use them at the command, but the Windows GUI does not seem to display B: as a drive. though I can navigate to it in the address bar.

What's up with this?

Floppy drives are all but dead, but Windows still reserves those drive letters for them for backwards compatibility. Yes, you can map drive to A: and B:, however if you have a floppy drive built in, or use a USB drive, then Windows will use A: and B: and It will show up with a floppy icon under My Computer. Unfortunately, I can only assume its by design (although I dont know why) that Windows wont show you drives mapped to A: or B: under My computer.

I didn't test with network shares, but it seems to have no problem at all with local SUBSTed drives. – Karan Jun 26 '13 at 1:48
interesting... i tested with network shares. maybe a bug? – Keltari Jun 26 '13 at 1:49
Perhaps... Can you test with local drives? – Karan Jun 26 '13 at 1:50

Windows 7 as a OS, Floppy was considered Out-Of-Date as the answer Keltari (user) shows. Although again yes if you use a USB Floppy Drive it will show that as in C:/ for the icons it has a present path for that image and drive letter let alone save one when a CD is used to install that drive.

Kinda makes sense now ... It could be a specific design decision to make the windows explorer GUI easier for 'regular' or less experienced users.

Someone reminded me that a non-existent drive B: could be used as a destination to copy from the actual drive A:. It was used by the diskcopy utility that duplicated disk images of floppies, and a prompt would display to swap disks when copying an individual file from floppy to floppy.

So windows explorer could prevent a user from getting the baffling "insert disk in drive B:" message, when they tried to drag individual files to a drive B: drop target by not displaying that as a target.

Did you see the comment I posted yesterday? Do you face the same issue with local SUBSTed drives as well not showing up as A: and B:? – Karan Jun 28 '13 at 1:33
Thanks Karan, both Subst and net map work just fine at the command line prompt - but I was wanting to see this in the GUI explorer, where I can't B to appear. – Rawheiser Jul 2 '13 at 15:58
So even if you SUBST a local dir (not a network location) as A: or B: (for example subst A: C:\Users), the drives don't show up in Explorer? – Karan Jul 2 '13 at 16:37
Yes that is correct, In Windows 7 they do not, haven't tried 8 yet but I am assuming it doesn't work there either. – Rawheiser Jul 2 '13 at 20:59
Weird. As you can see from my screenshot it works fine for me in Win7. – Karan Jul 3 '13 at 7:48
