The Drop Box tool creates a folder for each student in the course. Students are only able to access their own folder. Students and instructors can both place files in the folders.
The Drop Box mirrors the file management features and functionality of the Resources tool. (As with Resources, multiple files can also be uploaded using Drag and Drop.) The only difference is that Drop Box is an individual folder for each student within a particular site.
To access this tool, select Drop Box from the Tool Menu in the site.
