DOS error: parameter format incorrect
Updated: 11/06/2021 by Computer Hope
This error occurs while in the MS-DOS command line in Windows NT, 2000, XP, Vista, and later versions of Windows. It occurs when using the older command instead of cmd command when opening a command prompt.
Click Start, Run, and type cmd instead of command to access the command prompt. Once in this screen, perform the same command and you should not get the parameter format error.
