If you have a school account, either or not combined with a management account, you can share Presenter files among each other.
These accounts contain extra folders in the file manager. In addition to the private and community folders, there are also school and management folders. All Presenter files you make can be saved in these folders.
If you save a file in the school or management folder, your colleagues or your entire management board can also view your Presenter file and use for their own lessons.
