>>39696>>39697Most torrent clients like microtorrent, qbittorrent, and deluge are able to create torrents. It will be something along the lines of file>create new torrent>choose files.
From there once you have the torrent created and seeding on tour local machine, share the same .torrent file or a magnet link with other people.
That's about it I think.
I can't speak for the content of your torrent, but you should compress large folders into .zip or .rar files to make it easier, especially at that kind of total size.
