After all files are properly renamed, then
- Scan files
- Empty Trash
- Clean Bundles
- Optimize Database
We always tell everyone to NOT use the Multimedia share.
To remedy the database — Optimize it then restart Plex.
Your scheduled tasks should have it set to optimize every few days. If you’ve disabled it, turn it back on.
