## Notes
## Path exclusion file should look like this, with the FULL path (No # at the beginning of the line):
#/mnt/data/media/Videos/HD Movies/
#/mnt/data/media/Videos/Movies/
#/mnt/data/media/Videos/Anime/Naruto Shippuuden/Season 13/

## Name exclusion file should look like this with the FULL directory name for the show or movie (No # at the beginning of the line):
#Alice in Borderland (2020)
#Drunk History (UK)
#Ripley's Believe It or Not! (2000)
## You will need to narrow down which shows to include/exclude based on whether or not the Series actually uses "Episode ##" for the episode titles.
