qBittorrent official forums

Greetings all. I'm just starting to use qbittorrent to download large ortho files for Xplane scenery. My question is about seeding.
Does it stop once the program is shut down or do you have to stop it another way? Thanks.

You can either stop it by hand (clicking a torrent in the list then hitting "pause" button), or you can close qBittorrent.
Client applications such as qBittorrent only seed if they are running on your computer.
