I have been following this series on Youtube /watch?v=rr-9w2gITDM , i watched his 3rd episode and he has not made anymore so far. I am not looking to make the next windows, But I want to be able to make commands where the user can make directory's and files. How could i do this?

Here is a link to his ep03 source(I have the exact same thing with a few changes): http://adf.ly/131xdu

Thank you for any help.
