Once you've created a folder, you can rename it at any time.
Step 1: Click on the pencil icon
Step 2: Type the new name for the folder and click "save"
Step 3: Your folder is now renamed!
If you no longer need a folder, you can simply click on the "pencil" icon and click "delete folder"
Alternatively, if you want to keep the assignments and data, you can add these folders to an archive folder.
If there are assignments in a folder, you will not be able to delete it. This prevents you from deleting any student work by mistake.
