CD (Change Directory) is a command used to switch directories in MS-DOS. For example, if you needed to run Windows 3.11 from DOS, you would type:
Syntax
CHDIR [drive:][path]
CHDIR[..]
CD [drive:][path]
CD[..]
Examples
cd\
Goes to the highest level, the root of the drive.
cd..
Goes back one directory. For example, if you are within the C:\Windows\COMMAND> directory, this would take you to C:\Windows>
Windows 95, 98, and later versions have a feature in the CD command that allows you to go back more than one directory when using the dots. For example, typing: cd... with three dots after the cd would take you back two directories.
cd windows
If present, would take you into the Windows directory. Windows can be substituted with any other name.
cd\windows
If present, would first move back to the root of the drive and then go into the Windows directory.
cd windows\system32
If present, would move into the system32 directory located in the Windows directory. If at any time you need to see what directories are available in the directory you're currently in use the dir command.
cd
Typing cd alone will print the working directory. For example, if you're in c:\windows> and you type the cd it will print c:\windows. For those users who are familiar with Unix / Linux this could be thought of as doing the pwd (print working directory) command.
