The 20 MB hard disk can store as much data as 55

Your computer can read from and write to a hard disk
faster than when using a diskette.
You can store all your frequently used programs and
data files on the hard disk, reducing the amount of time

many powerful features that let you move, create, delete, and
rename files and directories, and view and execute files. See
“The XTREE Utility” in Chapter 3 or your MS-DOS reference
manual for instructions.

diskette drives. This helps you perform operations that normally
require two diskette drives.
For example, if you give a command to copy from one drive to
another, MS-DOS copies from the first diskette you place in the
drive to the computer’s memory. Then MS-DOS prompts you to
