I looked up in the canvasd guides how to load many files to my course. They showed how to download files as a zip file. But those options do not show when I click on Files with in my course.
I don't know if I understand your question. Are you wanting to add bulk files to Canvas? If so the this guide on How do I upload bulk files to a course? should help. If you are wanting upload Zipped files this guide should walk you through the process.
If that is not working, reach out to our support and they can look into you specific case. Just click on the help menu in your course and "report a problem".
Hope this helps,
