You may organize your dropbox folders into categories if you have many dropbox folders. For example, you can create separate categories for course units, summative projects, bonus assignments, and individual submissions. But categories are optional.
See Creating a Dropbox.

- On the Dropbox Folders page, click New Folder. (If you have already created a dropbox, click Edit Folder from the dropdown menu on the existing dropbox.)
- Click the New Category link beside the Category field.
- Enter a Name for the new category.
- Click Save.
