Profile Layout

Hi!
I have changed the layout to show the user's document (/view/documents/tmpl/default.php). This even works if i use the single link in my menu to the user's document. But there ist also a download tab in the user's profile and here the changes I have made are not visible. I have searched for another php-file where the layout of the user's document can be changed, but I found nothing. Where is my mistake?

Thank you,
Andreas
