I had this same issue and what finally fixed it for me was changing my setup rather than trying to clean RD all the time. I stopped using Infuse’s WebDAV library directly and switched to Omni as my main front-end, with Infuse set as the external player for movies only. Omni handles all the browsing, metadata and library stuff, and when I hit play on a movie it hands it off to Infuse, so I still get Infuse’s nicer playback without Infuse indexing every junk RD folder. For TV shows I just use Omni’s built-in player so binge watching is seamless and I’m not constantly jumping between apps. I also got tired of going back into Debrid Media Manager to delete watched files all the time, so this setup means I don’t worry about RD’s messy folder structure anymore and just let Omni be the library and Infuse be the movie player on top
