Individual Student File Repository (Art Lader)
This was orginially posted on Moodle.org Exchange. This will allow students to have a place to upload one file that they are working on so that they can download latter to work on.
Because this is a database, you can add additional file fields if you wish to have students able to upload more than one file at a time. The teacher approval is turned on in this sample so you can see how teacher would have to approve student submission for it to show for other students. Students can edit their own submissions so they can upload the new file right over the old one.
