Can I hide certain upload folders in media library [duplicate]

June 9, 2022 by Tarik Billa

Perhaps a bit quick and dirty, but this should work:

function media_library_hide_dlm_downloads($where) {
   if(isset($_POST['action']) && ( $_POST['action'] == 'query-attachments')) {
      $where .= ' AND guid NOT LIKE "%wp-content/uploads/dlm_downloads%"';
   }

   return $where;
}

add_filter('posts_where', 'media_library_hide_dlm_downloads');
