Hide "Folder" in Metadata Filter Contnet Type dropdown

Hi all,

I have "Content Type" selected as one of our options in our Metadata Filter on our library. It displays all our Content Types, but also displays "Folder". We don't use folders, folders are evil, and we don't want it in our Metadata Filter. We have already disabled making the New Folder command available. Where can I hide Folder from the list of Content Types that appear?

Thanks,

Kelly
