How do I link to a file in a Canvas text box?
Instructors can easily link to any file uploaded to their Canvas Files tool in Canvas tool that uses the Rich Content Editor. (These tools include Syllabus, Announcements, Assignments, Discussions, Classic Quizzes, and Pages)
Click on the "More" icon (three vertical dots), select the Documents icon, and select "Course Documents"
This displays an "Add" panel on the right displaying all of the files uploaded to the course site Files tool.
This automatically creates a link in the text box to the file in the Files tool.
When a student clicks on the link, the file will open in the Canvas document viewer.
If the file is a document that can be previewed, you can set the preview to automatically open inline. After the page is saved, the preview will appear on the page below the link.
