Created attachment 10 [details] directory structure needs improvement Currently we use the following directory structure to store a student's assignment submissions (e.g., see the attached picture): /student-number/assignment-title/assignment-submission.zip This structure is fine if the student takes only one course. But if he took multiple courses that have the same assignment-title, then there is a potential conflict. To avoid this, we could either use /student-number/course-code/assignment-title_assignement-id/assignment-submission.zip or use /student-number/course-code/semester/assignment-submission.zip Which one is better? -Hui
