Congratulations on graduating! You don’t want to lose all your hard work. You can take your files from your CCPS assigned OneDrive by visiting the following link.
Clicking on Learn More on that site will take you to the instructions on how to move your OneDrive for Business (CCPS assigned) files to your personal OneDrive account. If you do not already have a personal OneDrive account you will have to sign up for this using a personal email address (non-CCPS assigned email).
