By default, when you delete a post or page, any associated media files or attachments to that post do not get deleted. Keeping these orphan files to your server will eat up a lot of precious web space for no reason.
Using this plugin when you delete a post, any associated attachments will also get deleted automatically.
Before deleting any media file or attachment the plugin smartly checks that the attachment is not in use elsewhere, i.e. on any other post, page, or product.
