... I want to make a folder public to outsider (only for viewing the objects in it). but Zope asks for name and password. You may need to grant both "View" and "Access contents information" to "Anonymous".

When your objects need objects from outside the folder, then these objects grant "View" and "Access contents information" to "Anonyous". If the problem persists, abort the login request. You should then see an error page telling you which object can not be accessed. Check the permissions for that object. Dieter
