How to add file to one or more folders:
Click on a folder name to put that doc in just one folder (only takes one finger).
Command-click (Mac) or CTRL-click (Win) to put the document in two or more folders.
"One place, one finger. Two places, two fingers."
When you're ready, be sure to add your document to your class Drop folder so that your teacher can see it.
