@hotmuscletwi : The specific instructions will depend on which torrent app you're using but, basically, all of the major apps allow you to specify either a file or a folder when you create your torrent file and the process is virtually identical for both.
In qBittorrent, which I use, I bring up the Torrent Creator from the Tools menu, click the "Select folder" button, and point it at the folder where I've stored my content. The torrent creator does the rest, adding all of the files in the folder, as well as the top-level folder itself, to the torrent.
The upload process on the site is the same regardless of whether you're sharing a file or a folder.
