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:

•

•

You can use the DISKCOPY command to make an exact duplicate of a diskette.

You can use the COPY command to copy individual files.

•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.) The procedure 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.
