Recover Dropbox Files for Dropped Students

If a student submitted files to a dropbox folder and then dropped the course, the date and time of the student's submissions appear on the dropbox User Progress page (user progress for dropped students is accessible from the Reports page of the Classlist). However, any files submitted are not accessible unless the student is enrolled in a course offering. So you have to re-enroll a dropped student's user account to access any dropbox files submitted while that student was enrolled in the class.
