How do I delete a file or folder as an instructor?
You can delete a file in courses, groups, or personal files. This process also applies to deleting folders. Once a file is deleted, it cannot be recovered.
Note: The Unfiled Folder stores documents, graphics, and any other files from your account that you have posted to different areas of Canvas, such as Discussions. Deleting these items within current courses may create broken links and submissions.
Click the line item for the file . Click the Delete icon . Or click the Settings icon  and then click the Delete link .
