I'm not quite sure I have understood the concept of server files.

My understanding:

• I can go to a course and see all files I have access to in a course as student
• I have access to all files I've added to the course directly as student
• I have access to all files I've added to the course directly as teacher

My findings:
Students don't see any file in a course.
Teacher sees files he has uploaded to a course

What is intentuion of the repositiory?
Is it working in this way correct?
