PLEX is filling up my C: drive with Metadata when I wanted it to use the D: drive

Server Version#: Version 4.116.1
Player Version#: Not relevant
I installed PLEX on my D: drive that has plenty of room for everything PLEX. However, when I look at my C: drive. the directory path \AppData\Local\Plex Media Server\Metadata is up to 1.2 terabytes. How can I move this to the D: drive so my C: drive is free for my virtual machines and other things I need to run on the RAID drive D: not my SSD for BOOT drive C:. I looked through the KB from PLEX .

The article asked me to follow these steps.

  • Quit/exit your Plex Media Server
  • Copy the contents of the Plex data directory, which is here by default: %LOCALAPPDATA%Plex Media Server to the new location, for example: D:PlexPlex Media Server
  • Open the Windows Registry Editor (regedit.exe)
  • Navigate to HKEY_CURRENT_USERSoftwarePlex, Inc.Plex Media Server
  • Double-click on the LocalAppDataPath value and enter the new path, for example: D:PlexPlex Media Server
  • Restart your Plex Media Server

However, I opened regedit and do not even see the LocalAppDataPath in there to set. My guess is I should create the key but would like to get some guidance.

Correct.

Edit: you should however avoid installing the server executables outside the default location as this can open a different can of worms.

This just happened to me recently, too. All my data was on a separate drive, but suddenly my C drive is full. Ran WinDirStat and found out it’s Plex’s metadata folder rapidly eating up drive space when it was supposed to be on a different drive.

And, yes, I did change the path in Regedit quite a while ago, but it seems like an update must have deleted it. This really kind of pisses me off because now I have to redo the whole procedure that I’ve done before.
