# How to get a list of drive letters on a system through a windows shell (bat, cmd)?

How do I get a list of drive letters and their associated labels on a windows system through a bat file?

-

This will get most of it:

Net Use


If you have any drives mapped via subst you would also need to get those:

Subst


For completeness, you would do it like this in Powershell (if you are on windows 7 or have installed it):

gwmi win32_LogicalDisk -filter DriveType=4


You can also do it from the command prompt or a batch file using WMI like this:

wmic logicaldisk get caption,providername,drivetype,volumename

This doesn't list local disk drives like any internal hard drives or cdroms. Am I missing something? –  Chris Magnuson Sep 4 '09 at 21:12
Nope, I misunderstood the question. I thought that you only wanted mapped drives. I will edit. –  EBGreen Sep 4 '09 at 21:18
The wmic solution should give you everything. –  EBGreen Sep 4 '09 at 21:20
You need to remove the quotes from wmic logicaldisk get "caption,providername,drivetype" so that it is wmic logicaldisk get caption,providername,drivetype other wise it throws an error. EBGreen you have single handedly blown my mind for the day, I have never seen wmic even though I have been scripting various server builds for weeks and I am extremely excited to see what else I can do with it. Great job! –  Chris Magnuson Sep 4 '09 at 21:24
wmic logicaldisk get caption,providername,drivetype,volumename the VolumeName was what I was missing, if you update yours with that I will accept it as the answer. Thanks –  Chris Magnuson Sep 4 '09 at 21:31

To use diskpart, there is no need to create an intermediate file. Try:

echo list volume | diskpart

This is the best answer and returns the most info about the mounted drives in a beautiful format. –  ekerner May 29 '13 at 7:41
@echo off
cls
setlocal enabledelayedexpansion
set "_DRIVE.LETTERS.FREE=Z Y X W V U T S R Q P O N M L K J I H G F E D C B A "
for /f "skip=1 tokens=1,2 delims=: " %%a in ('wmic logicaldisk get deviceid^,volumename') do (
set "_DRIVE.LETTERS.USED=!_DRIVE.LETTERS.USED!%%a,%%b@"
set "_DRIVE.LETTERS.FREE=!_DRIVE.LETTERS.FREE:%%a =!"
)
set _DRIVE.LETTERS.USED=%_DRIVE.LETTERS.USED:~0,-2%
set _DRIVE.LETTERS.USED=%_DRIVE.LETTERS.USED:,@=, @%
set _DRIVE.LETTERS


Fast, flexible and efficient. Although a little complex.

I don't know what versions of Windows this works on but I just tested it on my Win 7 and XP machines and got the following output from both:  DRIVE LETTER(s):USED: " =" DRIVE LETTER(s):FREE: "!TMP_FREE_DRIVE_LETTERS!" –  John Gardeniers May 12 '11 at 0:44
Sorry, you need to put this in the beginning of the batch file. setlocal enabledelayedexpansion –  Dharma Leonardi May 12 '11 at 3:19
I've edited your answer to include the missing line. It works now. +1 –  John Gardeniers May 12 '11 at 3:31

inspired by Scott

for %i in (a b c d e f g h i j k l m n o p q r s t u v w x y z) do @%i: 2>nul && set/pz=%i <nul


also shows CD drive letter. no need to be admin.

simple and works –  Tyler Long Feb 27 '13 at 10:13
mountvol


sample output

\\?\Volume{11197e59-f977-11dd-afc6-111e6f6e6963}\
*** NO MOUNTING POINT ***

\\?\Volume{11197e59-f977-11dd-afc6-111e6f6e6963}\
D:\

\\?\Volume{11197e59-f977-11dd-afc6-111e6f6e6963}\
C:\

\\?\Volume{11197e59-f977-11dd-afc6-111e6f6e6963}\

If anyone is lucky enough to be using Vista (Vista Ultimate SP2 b6002, in my case) and the gwmi and wmic snippets given here don't work exactly, here is what I did to make it work.

For gwmi, if you receive no output, try changing the DriveType to 3. If still having problems, remove the -filter option altogether and analyze output.

gwmi win32_LogicalDisk -filter DriveType=3


For wmic, if you receive "Invalid GET Expression", then try putting the get expression in quotes:

wmic logicaldisk get "caption,providername,drivetype,volumename"

-

@echo off

echo list volume > scriptdiskpart

diskpart/s scriptdiskpart

del scriptdiskpart

pause

-
I tried this one and it didn't work. I think there needs to be a space in front of the /s but even with that change it didn't work. I put the above in a file, d.bat and I see the diskpart window flash up but then disappear and the cmd shell where I'm running this then shows the pause running. –  slm Dec 21 '11 at 3:27

Somewhat kludgy, but works from a batch file:

echo LIST VOLUME > temp.txt && diskpart /s temp.txt && del /q temp.txt

-
for %a in (c: d: e: f: g: h: i: j: k: l: m: n: o: p: q: r: s: t: u: v: w: x: y: z:) do @vol %a 2>&1 | find "drive"


I found the diskpart approach reports DVD drives with no disc inserted, and doesn't report SD cards with valid drive volumes

does not work for windows xp –  Tyler Long Feb 27 '13 at 10:15

Although it has enough answer, I'd like to add one when you want to use it in batch file. If you get "Invalid GET Expression", you could put a ^ before the ',', like below:

for /F "usebackq tokens=1,2,3,4 " %%i in (wmic logicaldisk get caption^,providername^,drivetype^,volumename 2^>NUL) do echo %%i %%l

-
What does this ^ do here? –  vonbrand Mar 27 '13 at 10:10
It is cmd.exe's escape character, similar to \ in Unix like shells. –  gimpf May 12 '13 at 11:39
for %%p in (a b c d e f g h i j k l m n o p q r s t u v w x y z) do if exist %%p:\nul your_command_and_parameters_here

This site has a much simpler set of calls:

http://en.code-bude.net/2013/02/23/show-all-drives-in-command-prompt/

Show local drives:

wmic logicaldisk get deviceid, volumename, description

If you want to show only drives of a particular type, the wmic command can be further expanded to include a where clause.

wmic logicaldisk where drivetype=2 get deviceid, volumename, description

Types

0 => Unknown

1 => No Root Directory

2 => Removable Disk

3 => Local Disk

4 => Network Drive

5 => Compact Disc

6 => RAM Disk

Um, wow. So if you can distill that into something that would actually just output the drive letters and labels that exist on the system that would be closer to the answer to the question though this is it least movement in the right direction. –  Chris Magnuson Sep 4 '09 at 21:16
I'm getting down-voted for providing a solution that meets the criteria? Wow... –  Scott Sep 5 '09 at 5:19
Well, for one thing, it produces errors for drives that exist but contain no media, such as a CD/DVD drive. –  Dennis Williamson Sep 6 '09 at 12:47
+1 for the idea –  Tyler Long Feb 27 '13 at 10:18
