The Columbia University default quota for course sites on Canvas is 1500MB.
If an instructor is looking to host large video files then CUIT can integrate Panopto into their course.
Additional file space is managed by CUIT. To request additional file space in Canvas contact courseworks@columbia.edu with your course information, semester, space requirements, and reason for the request.
