Windows Batch Script Get Current Drive name

Question

I have a batch file which is on a usb key. I need to know the drive name the batch is in.

Example, if it\'s E:\\mybatch.bat it should find E:\\ same thing for F:\\, G:\\

Answer 1

Beware

The existing answers to this question don't acknowledge that the question is actually asking about two different things:

1. the drive of the current working directory (“Get Current Drive name”); and
2. the drive of the batch file (“I need to know the drive name the batch is in”).

These can be different when the batch file is started from a working directory other than its residing location. Readers should therefore be clear on the difference before determining which solution is relevant to their case.

Drive of the current working directory

%CD:~0,2%

This takes the full current working directory and trims it down to the first two characters, which will be a drive letter and a colon, e.g. C:.

Drive of the batch file itself

%~d0

This trims the full path of the batch file (in %0) to just a drive letter and a colon, e.g. C:.
