Hiding and showing windows on the desktop
You can hide all windows except those of the active program by choosing
Hide Others from the Application menu.
The other programs remain open even though their windows are hidden.
When you switch to another program, its windows become visible again.
If you want to see all the open windows, choose Show All from the
Application menu.
Protecting the information on a disk
When you have a valuable document like a birth certificate, you probably
make an extra copy of it for safekeeping. Similarly, you should make a copy of
the documents you create on your computer. The extra copy is called a
backup, and the process of making the copy is called backing up.
Once you have a backup, you’re protected from accidentally losing the
information on your hard disk. In the unlikely event that something happens
to your hard disk, you can easily get the information back.
Your computer’s hard disk comes with a lot of valuable information already
stored on it, including system software and some application programs. The
Macintosh Performa CD contains a backup copy of all the system software and
application programs that came with your computer. See the Macintosh
Performa CD booklet for instructions on using the CD to reinstall software.
Making backup copies of the documents you create
m You can back up files stored on your hard disk by copying them to
floppy disks.
m You can back up an entire floppy disk by copying it to another floppy disk
of the same capacity or larger, or by copying it to a hard disk.
m You can use a commercial backup program to copy new and changed files
from a hard disk to another hard disk, to a tape drive, or to a series of
floppy disks.
m If your computer is on a network, you may be able to back up files by
copying them to a shared disk on the network.
