Mine is a little more complicated, but it gives me piece of mind and the ability to see what each program is doing, and to manually sort files if sonarr/radarr stop working for whatever reason
My folder structure is
downloads
incomplete
complete
tv
movies
video
tv
movies
Each component of my stack is isolated using docker and can only acess what it needs to. Sonarr, Radarr and qbittorrent are configured to use labels to keep the downloads directory sorted.
I can post my docker-compose.yml file if you want to have a look.
