There isn't difference when the Security is on, both folders (authorized and not authorized) aren't showed, I can see authorized and not authorized only if the security ("Protect shared content with user accounts") is disabled
Disabling security from the admin page
"Protect shared content with user accounts"
I can see the books and comics

Yep, enabling the security and use the absolute path on the folder shows the comics, thanks
