I am creating folder using JavaScript API folder = dest.createFolder("foldername"); I want to make that folder private to one group only i.e. Only one group can see it and add content into it. I can set permissions like folder.setPermission("Collaborator","GROUPS_groupname"); But other users also can see this folder and site contributors and collobrators also can add content into it. is it possible to hide to everyone except one group?
