If you site is small and/or new, then consider re-arranging your directory structure so that robots can be controlled by directory, not by file-type. If it's a large established site, and cahanges to the existing directory structure are not feasible, then you'll just have to list out the Disallowed files one-by-one if they are in the same directory as "allowed" content.
