The menu app and the folder containing all the PDF’s ranges in size from 800MB for Elementary packages to 1.5GB for High School and Junior College packages. The folder can be stored either on your building server or on selected teacher laptops. The menu app can be “pushed” to individual desktops using whatever software you currently use to control apps on all the PC’s you support, or included in a system image for distribution to every machine in your building (or district if you have a county-wide license).
