Removing parent directory

Hi –

Nice simple skin. One question – is there a way to remove the parent directory in the skin? For my folks, they inevitably keep clicking back and back until they reach the video addons and end up corrupting the files..dont ask me how lol. But is there a way to remove that ability to go back by clicking the dots at the top of a list for example. Would REALLY like to be able to take that ability out.

Thanks
