Parameter format incorrect or parameter format not correct error in DOS

Updated: 04/26/2017 by Computer Hope

Windows DOS command prompt windowThis error occurs while in the MS-DOS command line in Windows NT, 2000, XP, Vista, and later versions of Windows. It is caused by using the older command instead of cmd command when opening a command prompt.

Click Start, Run, and type in cmd instead of command to get to the command prompt. Once in this screen, you should be able to perform the same command without getting the parameter format error.
