There is an awesome plugin WP Download Manager, which allows us to upload and manage files in a very comfortable way. But unfortunately, it has no deep file search functionality.
This WPFTS add-on plugin makes a “bridge” for WPFTS to let it understand WP Download Manager’s files and implement the search on them by content.
