1. Introduction

As you learn in this unit, there are multiple ways of sharing resources. Creating a Folder, uploading a File like Word document, sharing a URL to an external website, or attaching an image to the forum post are just some of the examples. Decision regarding the tool is driven by your purpose and the format of the existing resource. Moodle is a flexible system however, as any technology presents some constrains to the users. It is worth to know what the constrains course creator may meet when working with resources. Let's start with the file format and then look into other constrains.
