Grading a dropbox folder

I discovered an efficiency in using the plagiarism detection tool for grading. The originality report is grouped by folder, so I open that in one browser window and the list of students with submissions in another browser window. The Turnitin window has navigation controls to move from one file to another, so using this navigation means I can provide feedback without having to download all the files. I do need to encourage students to provide their names in the text of the file or the filename, as otherwise I have to do some sleuthing to match the submission to the student.
