How to change current working directory using a batch file

Try this

chdir /d D:\Work\Root

Enjoy rooting ;)

Specify /D to change the drive also.

CD /D %root%

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.
