Ending a work session
When you have finished your work -- with a program or for the day -- it is
important to save your work, and to consider making backup copies of
important items.
Quitting a program
When you are finished using a program, you should save the work you want to
keep and then use the Quit command to return to the desktop.
1. For each open document to which you have made changes that you want to
keep, choose Save from the File menu.
Even though most programs will prompt you to save if you try to quit before
saving new work, it is good practice to save your work before you quit,
rather than to rely on a program's safeguards.
2. Choose Quit from the File menu.
Backing up your work
If you do not routinely make backup copies of your work as you go along, be
sure to copy any important documents you have revised during the session. The
safest backup practice is to copy your work onto a disk other than the one on
which the original documents are stored.
1. Insert a backup disk in a disk drive.
You can back up by making copies on the same disk, but making copies of your
work on separate disks is advisable as well.
If you have only one floppy disk drive, you will need to eject the disk
currently in the drive to insert the backup disk.
2. Copy your files by dragging their icons to the icon of the backup disk
(or into a folder on the backup disk).
