Correct. Your manual added torrents only.

But to be clear your downloads folder should ideally have subdirectories in it, or at least that’s what I have.

*Completed Downloads", with subdirectories for movies, series, audio, books, blackhole_movies, blackhole_series, and any other category you have.

In your download client you then make sure to set it up that all downloads get a category that then dumps the completed download into the corresponding folder.

So when a movie gets added by radarr its assigned a category of movies in your download client, and when it finishes downloading it goes to the completed/movies folder. And similar if a series gets added by sonarr a category of series gets assigned and moved to the completed/series folder.

Any torrent you add manually you would then assign either blackhole movies or series and your download client would then move it to that completed folder. Radarr would then see new files appear and try and import them as it regularly will now scan that blackhole folder.
