6). Copy over the files with .dsl extension from the left to the right side ( to "/mnt/sda1/optional" )
7). Next time you boot you will find the extensions you saved in the Menu --> MyDSL

Now you can take your USB-Stick to every computer you can find ( from Iceland to Antarctica ) that boots from USB and you will have your favorite OS + favorite programs booted in seconds.
Have fun !!
