The answer should be pretty obvious:
--format '{n}/Season {s}/{n} {s00e00} {t}'


Yes... I tried that way as well. I need a way to explicitly imply the space.

Unfortunatly that doesn't work either.
root@NAS:/mnt/user/local_data/complete# filebot -rename --action test "/mnt/user/local_data ...

This is probably a really dumb question, but I am having an issue adding a space to the season output format while using filebot.

filebot -rename --action test "/mnt/user/local_data/complete" --format '{n}/Season.{s}/{n}.{s00e00}.{t}' --db TheTVDB --output '/mnt/user/tv_shows/'
