This question came to me in a direct message. Rather than answering it privately I thought I'd post it here and left the community respond so that others with the same questions might benefit.
Direct message begins:
Im asking this questions in the point of view as a student. Because of my intimate knowledge of Canvas I was one of those students who would organize and delete my submissions now and then. A few weeks ago we had an update where students can now download all submissions. I am struggling with this a bit because of these reasons
1) I cannot pick and choose the courses
2) I no longer have access to the actual files --> A realize this is good to prevent students from deleting submissions
3) every time I download, it takes ALL my courses of my canvas student lifetime --> that includes both in sandboxes and real SIS courses.
4) pretty cool it lists all the courses that I am teacher in, but not the courses I am a student (perhaps this is because of the way Files area is linked to the course).
Or is the problem because of my dual role in Canvas?
