Re: using qbittorrent
When using qbitorent or any other torrent client the download will show "seeding" when finished.
The torrent on your computer is then "seeding" to others downloading.
Any .iso files can be checked using the appropriate checksum provided with the torrent.
If you wish to stop the torrent then right click and select delete, this will remove the torrent but leave the data in your downloads folder.
Hope this helps
