Don't know if there's a proper way to do this but as a terrible hack you can edit jsp/repository/defaultView.jsp (I think - typing from memory), to add <c: if> tags to check for the resource name and skip outputting it if it's one you don't want. Just don't change the folder name in the repository, or upgrade over top of your changes. Those are some reasons it's a terrible hack, although the end result would just be that users could see them again, so it's not the worst.
