Google Drive repository
Note: You are currently viewing documentation for Moodle 3.0. Up-to-date documentation for the latest stable version of Moodle may be available here: Google Drive repository.
Google Docs can serve both as a Repository from which users can "pull" files they need for their course and also a Portfolio into which they can "push" files they want to keep. Both options need to be enabled by the administrator before they are available for teachers and students.
