The Professional Master Key Utilities are an evolving group of programs designed to open the doors into your MS-DOS disks. They give you the flexibility, ease of use, and power to manipulate and change your disks in many ways that you weren't able to previously. The programs are user friendly, fast, and very powerful. There are eight programs in the utilities. You can run all of the utilities from one menu, so you won't have to remember all of the commands. There is also an installation program that lets you configure the options and colors of the programs in any way you want.
