@lazyreadr: On which FW version is that?
The script double-checks the config edit, so if you're saying that it went fine, and yet it's ineffective, the only logical explanation would be that you're running the one single FW release that started scanning hidden directories, but didn't yet support that config entry...
(Also: no, don't do anything from within Nickel, as that will trigger deletion of those files, which we kinda need
).
