Hi Robin… I assume you are talking about the plex file on C drive that contains all your metadata, cache and backups etc. ??? I had same problem my C drive was nearly full… I found this solution that worked well for me:
How to Move Plex MetaData to a Separate Drive 2020. This is how to move your Plex MetaData to a different drive, preferably an SSD. I also demonstrate how to move the transcoder cache folder as well as the backups folder to a new location. If you are having a difficult time following along here is a written version of the Tutorial.
