How to change current working directory using a batch file

Question

I need some help in writing a batch file. I have a path stored in a variable root as follows:

set root=D:\Work\Root

Then I am changing my working directory to this root as follows:

cd %root%

When I execute this batch file from anywhere on the D drive this is done successfully. But when I execute the same batch file from some other drive, cd %root% doesn't work.

Is there a way I can get the drive letter from the root variable? I can then change the current directory to this drive first and then cd %root% shall work.

Answer 1

Specify /D to change the drive also.

CD /D %root%

Answer 2

Just use cd /d %root% to switch driver letters and change directories.

Alternatively, use pushd %root% to switch drive letters when changing directories as well as storing the previous directory on a stack so you can use popd to switch back.

Note that pushd will also allow you to change directories to a network share. It will actually map a network drive for you, then unmap it when you execute the popd for that directory.

Answer 3

Try this

chdir /d D:\Work\Root

Answer 4

A simpler syntax might be

pushd %root%
