CMD is a Windows command script - the same idea as a .bat file but interpreted by the newer Windows NT command processor (cmd.exe), with a few extra features. Windows NT introduced .cmd in 1993 to distinguish its scripts from legacy MS-DOS .bat files that ran under COMMAND.COM. Analyser handles .CMD alongside related formats such as .HTML, .CSS, .JS and more. In Analyser's format library, .CMD sits in the Data & code category.
