Recently I installed qBitTorrent so I could download some episodes of a Creative Commons-licensed TV series. I simply used
apt-get install qbittorrent, ran
qbittorrent, then added the torrent files, and pressed "start". I noticed that the series would take too long to download, so I quit qBitTorrent when it was at 10%. The next day, I launched qBitTorrent again, and was surprised to find the downloads complete. Either the 2.5 GBs downloaded within 3 seconds or something else occurred.
Does BitTorrent continue to exchange files after starting the download in qBitTorrent and then quitting qBitTorrent?
