How to Delete a Student's Moodle Assignment Submission

We received a request from an instructor recently:

"I need to delete a student's submission to a Moodle assignment (she accidentally uploaded the wrong assignment)."
Our reply:

Moodle handles that a little differently than we might prefer. Depending on whether you have the Assignment settings configured, your student may or may not be able to simply edit or make a second submission with the correct file. Either way, you should be able to:

1. click into the Assignment
2. click the "View all submissions" button
3. select the checkbox to the left of the student's name
4. click the "With selected…" dropdown, "unlock submissions" and the "Go" button:

That should enable to student to resubmit to the Moodle Assignment with the proper file.

Yes, it would be more straightforward if there was a "delete submission" option in that dropdown menu, but I think Moodle wants to keep the submitted file on a "better to have and not need than need and not have" theme.
