How do I download all submissions for a particular assignment?

[r_w_kaye]

I am investigating cases of plagiarism on an assignment and need to download ALL submissions for that assignment (a file upload) from all students, NOT just the most recent submission for each student.

It would be completely unreasonable in terms of my time to check and download each file individually.  I need to download the lot in one go as a zip file.  The only things I know about on canvas select the most recent file from each student, whereas the cheating I am investigating concerns (or is more obvious from) less recent files.

Thank you

 @r_w_kaye , as you've aptly stated, while instructors can download all submissions for a specific assignment, the .zip file will only contain the students' latest submissions to that assignment; that's documented in How do I download all student submissions for an assignment? 

I found a recent conversation where members were brainstorming a solution for this: API: Download all assignment submissions?
