Adding Files to Your Course
Throughout your course creating, you will likely want to upload files for your students to access. If you want to include images in your lessons, or make handouts available for students to download, you need to make sure you've uploaded them to your course first. Here's how:
First, make sure you're in edX Studio.
Then, from the "Content" drop-down menu, select "Files & Uploads"
This is your "Files & Uploads" page, where you can manage all the files you add to your course.
You'll notice that for every file you upload, two URLs are generated. The Studio URL is for adding links to the file in course components. The Web URL is for linking to the file outside edX, such as in email. Students can only see a file if you create a link to it.
90% of the time, you'll want to use the Studio URL.
