That’s odd. CP is configured the same way and the movie folder gets deleted.
Sonarr knows what the download folder is since it is set in Drone Factory under Settings > Download Client. Perhaps you can use find to search for a folder in that directory matching the file name and if successful, delete it. Just thinking out loud here.
Maybe we should include clinton.hall to the convo.
@ptr727 Sorry for taking over your post. I thought our issues were related.
