Folder resource
From MoodleDocs
A folder allows a teacher to display several course resources together. The resources may be of different types and they may be uploaded in one go, as a zipped folder which is then unzipped, or they may be added one at a time to an empty folder on the course page.
Using a folder to display resources is neater than displaying files one by one in a list. It takes up less space on the course page. )However, the folder settings allow for the files to be displayed on the course page if required.)
{{New features}] An optional setting allows the teacher to show a download button in the folder so students may download the files as a zipped folder for viewing offline.
