Set up a plexignore (pasted below) - and yes it does have the correct extension as well.
# Ignore directories containg the word “[Extras]”
G:\TV 00-EZ\Doctor Who [1963]*[Extras]*
# Ignore files with the extension “.PDF”
.PDF
# Ignore all files with “extra” in the name
Extra.*
It’s working for the most part, but then keeps randomly adding extras into other series.
They’re all labelled correctly as well, the files it’s adding randomly have the word Extra in their title & the folder that contains them also has the word [Extras] in them,
and no amount of tinkering with the ignore folder structure will remove them.
