[folder] won't work under certain conditions

    i don't know if it's intended, but it's not stated so in the help file or reference.
    Those conditions are : if the queried folder path is outside max preferences path, and if you don't specify a type of files with a (types) message.
    In this condition [folder] gives no output bare a 0 from the right outlet, and will not report any error.
