If a native program requires a shared library and there is not enough memory
available for the shared library, you’ll see a message that the program could
not be opened because of insufficient system memory. If this happens, see the
“Memory” topic of Macintosh Guide, available in the Guide (h) menu, for
instructions on turning on virtual memory.
If a required shared library is missing, you’ll see a message that the program
could not be opened because the shared library could not be found. If this
happens, follow the directions that came with your program to reinstall the
program. If the shared library is still missing, contact the program’s
manufacturer for assistance.
Backing up your files
Making backup copies of important files is good protection against possible
damage to the originals.
m Your hard disk contains disk images of system software and the application
programs that came with your computer. If you have an external floppy
disk drive with an adapter or a dock, you can make disks from these
images using the Floppy Disk Maker application program. (Instructions for
using Floppy Disk Maker with a floppy disk drive are presented in the next
section, “Making Software Disks.”)
m You can back up an entire floppy disk by copying it to another floppy disk,
or 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 can back up files by copying them to
a shared disk on the network.
m You can back up files by copying them from one computer to the other
using SCSI disk mode. (See “Using Your Macintosh PowerBook as a
Hard Disk” in the “Connecting SCSI Devices” section in Chapter 3 for
more information on SCSI disk mode.)
