Moodle provides an easy way for a teacher to present materials to their students. These materials may take the form of files (Word documents, PDF files, Excel spreadsheets, etc.) displayed on the page as individual items or bundled together inside folders.
To add files to a Moodle course, you must first ensure you have the editing turned on. To do that, you have to select the Actions menu gear icon and click on Turn editing on.
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. Once you have created a folder you can still add files to it.
