Before the advent of completely digital, cloud-based, or file-based activations, Rockwell utilized physical media for copy protection. A "Master Disk" (often a 3.5-inch floppy disk or a specifically encoded CD-ROM) contained a hidden, proprietary license file (usually known as EVMOVE or MoveBy95 activation). The software required this physical token to move the license key onto the host computer's hard drive to unlock the full, paid version of the software. 2.
