I imported grades web pages, and received a warning to "delete your obsolete grades files". How do I do this?

To delete your previously imported grades files to make room for new grades files, go to your Update Grades page by clicking the "Update" link for your Grades page on your Update Index, and then click "Reset Gradebook to Default" (click "Delete All Grades" if that option is displayed on the Update Grades page instead).
