Copying Data
It’s very important to keep backup diskettes containing copies of the files you
create. You can copy data and program files several ways:
l
You can use the DISKCOPY command to make an exact duplicate of a
diskette.
l
You can use the COPY command to copy individual files.
l
You can use the BACKUP command to back up the files on a hard disk
or diskette in a compressed format.
Note
An easy way to perform the functions listed above is through the MENU
and XTREE programs. See the sections on MENU and XTREE later in this
chapter. You can also use the MS-DOS XCOPY command to copy one or
more files; see your MS-DOS manual for details.
Using the DISKCOPY command
The DISKCOPY command lets you create an exact duplicate of one diskette
onto another diskette. (You cannot use DISKCOPY to copy to or from a
hard disk.) Th
e
p
rocedure for copying diskettes depends on whether you
have one or two diskette drives. Follow the instructions below for your
computer model.
Using DISKCOPY with two diskette drives:
When you use the DISKCOPY command with two diskette drives, be sure
to specify both diskette drives (A: and B:). If you don’t, MS-DOS copies the
diskette in drive A to a second diskette that you insert in drive A, requiring
you to swap diskettes during the copy process. (MS-DOS displays prompts
that tell you when you need to change diskettes.)
1.
Make sure your original diskette is write-protected. (See Chapter 3 for
instructions.)
2.
Insert your working copy of the Startup/Operating 1 diskette in drive A.
