How to SET a variable to the path of parent directory on windows?

Question

Struggling with command line again, I have figure out that I can store the current working directory in a variable like so:

SET current=%cd%

<

Answer 1

Move up a directory, remembering the current, set the parent, and then pop down a directory, back to where you started

@echo off
set current=%cd%
pushd ..
set parent=%cd%
popd

echo current %current%
echo parent %parent%
