Recently I have been trying to find an way to efficiently find and delete all the episodes that I no longer need (I need to move my 3tb of files onto a new drive, so slimming down first is a good thing)
I wrote a C# program to link Kodi and Sonarr together (for TV Shows) and then mark the Sonarr show if it has been watched. I can then easily delete episodes in bulk that have been watched (in Kodi).
This is just a Windows Forms app for me, but I would be willing to work with the Devs here to move it into Sonarr if there seems to be interest for it.
We’ve talked about it from the perspective of being able to delete episodes automatically once they have been watched:
And we’ve considered it as part of integrating with trakt (at the time we were using trakt for metadata before v2 was released and in our experience handled it poorly).
We haven’t ruled out trakt integration, but we are hesitant. The nice thing with trakt integration was a single point of integration, versus adding support for every media player. I wouldn’t completely rule out support for going directly to the client, but being able to do it effectively for the clients we currently support would almost certainly be required.
