Can't find Plex database files

[xm41907]

I have Plex on my NAS and about to upgrade the hard drive, but I can't seem to access the database files. They supposedly are found at:/home/plex/Library/Application Support/Plex Media Server/Plug-in Support/Databases, but I do not have a home folder in my accessible folders. I know there is a root directory where my shared drive is:/mnt/md0/appdata/Media/ but the furthest up I can access is the appdata folder. How to get the higher up folders?

At the user directory level, click "User" to enter the user directory, and you will see the "plex" folder.
