Moodle will be closing down soon.
If you still use Moodle's Private Files to transfer work between school and home, please download anything you still need and consider using Google Drive (drive.google.com).
If you log into Google with your Google Classroom account (eg. firstname.lastname@example.org) you'll receive unlimited storage space. Google Drive is very easy to use and can also be installed on a PC or used as a phone/tablet app.
