ZeroOne is a tiny and very easy to use application that allows you to perform different file tasks using binary code.Only two buttons are needed for input - Zero and One. So the editor is called ZeroOne, or 'zo' for short.If you enter 'esc' (by typing 0011011) you enter 'Command mode'. In command mode there are three commands - 'o' (open), 's' (save) and 'q' (quit).
