Thank you for the prompt reply. I am using Windows Defender in Win10 Pro v.1909 and Malwarebytes v.4.1.0.56 (free).
I may move this folder off my boot drive to a spare SSD hard drive if it tends to get as large as before when I also had my music indexed it grew to over 1 million files & folders.
Thanks for the link. I have read through it before so I knew this was option. My boot drive is a 128 GB SSD and the other is a 256. Eventually I may dedicate it to Plex, good idea. This is the first in about 4 years I have not backed up Plex or preserved it some way and started from scratch.
You can combine the efforts and copy the plex data folder now to this SSD.
Save also the registry branch mentioned here: https://support.plex.tv/articles/201539237-backing-up-plex-media-server-data/
Then you are free to scrub the C: drive and install Windows 10 cleanly.
Afterwards import the registry branch and reroute the plex data folder to its new location and you’re good to go with all old Plex data intact.
That sounds awesome and I wish I talked to you sooner, after playing with Win2004 for awhile I made an image of it and this time instead of bringing back the image I had saved I decided to go with a clean install of v.1909. I’ve alreaady let Plex index everything, except this time I left out the 300K+ music files. I also un-checked ‘Enable cinema trailers’ and ‘enable video preview thumbnails’ on all the video libraries. I thought I would see how how large ‘\AppData\Local\Plex Media Server’ folder grew to with that config. and it’s much better. Now I’m just tweaking settings. Still, thanks for the link.
