The Windows cmd command

[Drive:] Change current driver

Example: E: Causes the current drive to be an e-disk, and the current directory does not change.

CD [drive:] [path] changes the current directory of the Drives

CD [/d] [drive:] [path] changes the current directory of current drives and drives

Example: CD E:\joan\joansky changes the current directory of the E-disk for Joan\joansky, the current drive has not changed.

Example: CD e:\joan\joansky[carriage return] e: At this time the current drive is the e-disk, and the current directory of the E-drive is Joan\joansky

CD/D E:\joan\joansky at this time the current drive is the e disk, and the current directory of e disk is Joan\joansky

CD [\] back to the root directory of the current drive

CD [..] Back to previous level

When you are in the current drive, you can use a relative path when you want to enter the directory of the current drive

Example: The current drive is E:\>, then you can enter the CD \joan\joansky directly into the e:\joan\joansky>

Such a command is wrong when the directory to be entered is not in the current drive. At this point you need to use the absolute path i.e. CD E:\joan\joansky
