Folders are a useful way to group content together and now have the option to allow students to preview the folder contents on the main course page as well as an optional [Download folder] button to download the contents.
In the “Edit Settings” interface for the folder, set “Display folder contents” to “Inline on a course page” to display a preview of the folder contents. Check the box for “Show download folder button” if you would like the [Download folder] button to display.
Sometimes an instructor may want to have students share files with the class. By making a permission change, students can upload files to a Moodle Folder. Note: students will be able to view and delete any files in this folder.
