Change directory?

Why cant I change directory in my python 3.8
I have a PY4E file under

C:\Users\LGU6279\Desktop\PY4E

what do I need to type in my CMD prompt to get it to CD to PY4E?

Hello!

What do you mean by:
to get it to CD to PY4E?

If this is your target folder,
I think you can type cd "C:\Users\LGU6279\Desktop\PY4E"

You can go one level up with cd ..
and one level down with cd foldername.

If you want to see the folders and files in your current folder,
you can use dir (Windows) or ls (Linux).
