There is plenty of metadata to save, unless you cleared out everything under Appdata/Plex Media Server and not just the Cache folder.
If you did only clear out the cache folder, use my advice above.
If you however want to throw away everything, do this:
- take a single drive (preferably internal, SSD)
- format it with NTFS
- tell Plex to use it as the location for the Plex data folder (basically steps 5 – 8 from this procedure: Moving Metadata on Windows - #3 by OttoKerner )
- delete everything in
Appdata/Plex Media Server(the old location of the Plex data folder)
