Back Up Explain Everything to Google Drive
Explain Everything PROJECTS on the iPad are only saved LOCALLY by default. To back up your projects, you must SEPARATELY choose to back up / save each project somewhere else. Google Drive is a great choice, since teachers have unlimited storage space on Google Drive and it's managed by our school IT staff.
This 42 second video shows the steps for backing up an Explain Everything project to Google Drive. These steps are also detailed (with screenshots) on this support article. Since these support resources are a few years old, some of the menu item names in Explain Everything might have changed slightly, but the process and basic steps are the same.
Backing up / saving an Explain Everything project is separate / different from exporting a final project video, which is generally shared via YouTube or Google Drive with students.
