You appear to have installed the program files of Plex onto drive F:
But the Plex data folder is still residing on drive C:
This should be the other way around.
No, really.
Uninstall plex from F:
- Stop/quit/end Plex Server with the tray icon
- deinstall Plex Server with the regular ‘Apps’ control panel of Windows (do not use 3rd party ‘Uninstaller’ software like Revo etc.)
- for safety, reboot Windows
- download the installation exe of the newer version and install it, this time again on C:
(If you want to install an older version of PMS, take a look into %LOCALAPPDATA%\Plex Media Server\Updates)
When you have done that, move the plex data folder to a location where it has space to grow. However, you should avoid to move it onto the same mechanical hard drive which also houses your media files: Moving Metadata on Windows
