Plexamp times out as per this post so I can’t tell you exactly.
There may be some mp3 files there also but I’d say your calculation is accurate give or take 20%.
It seems like my NAS is too slow to deal with this amount of data.
But when I managed to add it to the Shield PMS it was running reasonably well except I’d run out of metadata storage due to the reason in this post.
I can’t help to get a feeling from your responses that there is not really much interest in optimising the image size within the metadata folders - Im really surprised tbh, if I was in a position to make the product I work on more efficient and save 1000’s of people storage then I’d jump at it and push it home.
I did read in another Plex forum post that metadata was not removed when libraries were removed so users would have 3 sets of the same metadata but I have wiped the drive and/or the shield 5 times and on the NAS twice deleted the Plex Media Server drive.
Initially I thought the DB was getting corrupted on the shield so thought to copy the PMS from NAS to Shield - this takes 3 days thanks to Fat 32 file system (ext Plex formatted ssd drive) that’s when I confirmed both NAS and Shield produce pretty much the same amount of metadata.
