Making Backup Copies
Copy all diskettes that contain programs. After you make your
copies, store the originals in a safe place away from your
working diskettes and use only the copies.
For general instructions on copying diskettes or hard disk files,
see Chapter 3 or your MS-DOS Reference Manual.
Write-Protecting Diskettes
You can write-protect a diskette to prevent its data from being
altered. When a diskette is write-protected, you can copy data
from it, but you cannot store new data, modify existing data,
erase files, or format the diskette.
The write-protect mechanism is a small switch on the lower-
right corner on the back of the diskette. To write-protect the
diskette, slide the switch down toward the edge of the diskette
to expose a small opening.
