Another way of moving through the directory tree quickly
involves the use of a similar command:
C>CD\
This command will take you directly to the root directory of
the current disk drive. This can be useful if you get “lost” in a

The next step in organizing your hard disk involves copying
the external command files from the MS-DOS install diskette
