Once a file has been successfully submitted to an assignment submission folder, you can’t delete it. However, if you have the ability to make another submission, re-submit the file and make sure to also contact your instructor and let them know that you are re-submitting a file to the assignment submission folder.
If you don’t have the ability to make another submission, contact your instructor and let them know that you would like to re-submit a file to the assignments submission folder.
