 When a user clicks on one of the titles, the film is downloaded via the BitTorrent protocol.As with other BitTorrent clients, as soon as Popcorn Time starts to download a film, it also starts to share the downloaded content with other users (in technical terms, it seeds the torrent to others in the BitTorrent swarm).It continues to make the downloaded content available to others until the movie is deleted, which is normally done automatically once the application is closed.
