Microsoft's first operating system was called "DOS"—Disk Operating System. It is still inside every Windows system, and those who seek it (now called the "Command Line") can find it. The Command Line is a bare-bones control of the computer, and it doesn't correct mistakes or simplify things for you like Windows (sometimes) does. Still, the Command Line is a welcome simplification itself, in that you can sidestep the frequent requirement to go from window to window, accessing File Explorer, accessing the Task Manager, etc. Some tasks you can do in a couple of keystrokes at the Command Line. We have a library of tips to take you to your first experience with Command Line and then from moving files one-by-one in Windows to moving hundreds at a time, from muttering to yourself at renaming dozens of files with Windows to whistling happily as you do the same thing with a few keystrokes in Command Line. Command Line is "old school," but it doesn't have the operating decorum of Windows, and sometimes that can be a good thing.
