Find USB Drive letter

Question

I need to get the drive letter of the usb pen drive.the command CHDIR >drive.txt gives me the drive letter L:.How do I read/get this info \"L:\" without quotes into a variab

Answer 1

Whatever chdir outputs can also be used by the pseudo-variable %CD%. So you already have a variable with that information.

Otherwise you can use for:

for /f "delims=" %%x in ('chdir') do set "drive=%%x"

But I think %CD% is much easier :-)

EDIT: You said that with the quotes already. You won't have any quotes in the variable unless you want them in there.

As for the trailing backslash: You can use the following instead of %CD%:

%CD:~0,-1%

which will expand %CD% and remove the last character, which you know is the backslash.

Still, will only work if you're in the root directory of that drive. Otherwise you can also use

for %%x in (%cd%) do @set drive=%%~dx
