Dropbox allows you to store and share all of your files, from photos and videos to music and documents. You can access your files from any computer, tablet, or mobile device, using an app or the Dropbox website. If there’s a failure with your device or your files, they would be safely backed up with the Dropbox cloud.
This is a must-have for teachers & classrooms. It makes getting to your "stuff"a lot more convenient - no matter where you are.
