Thinking about this, I did run clean up appdata, in which Plex did link to my tv shows and movies only, but does not explain any other shares on the HDD. - I had pictures which I migrated over, but still have a copy on my computer (thankfully) which did not have any link to any dockers.
If anything, this may be the likelier scenario of the 2. ZeroTier was setup so that I could provide access to my family members.
Thanks for the explanation on that, as it did not occur to me that this was standard if there were no cache pool as I only seem to notice this now after all files are gone.
I can only see 1 file in me cache drive in my anime folder, and 2 TV show series (not complete), which I'm assuming are on my cache drive.
In regards to the share cfg files. I'm not sure how this happened as I'm trying to figure this out.
Clean Up Appdata was run but backup was run at the time of setup, perhaps about 1 week ago - which does not seem to be present when trying to restore.
