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

Question

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

Answer 1

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

Answer 2

Somewhat kludgy, but works from a batch file:

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

Answer 3

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"
