3 Hit the ¿ key or click OK
To save your working file automatically,
1 Choose Save Options... from the Options Menu
2 Click the Automatic save every: checkbox
3 Enter a number from 1 to 60 minutes
4 Hit the ¿ key or click OK
Tip
With the
Automatic save option on, you will never loose more minutes of
work than you entered in the minutes box, even if your computer
crashes or the power fails.
With the
Backup option on, you will not accidentally overwrite files
unless you save again (that overwrites your backup, too!).
Note
With both
options on, you will have three versions (generations) of your
working file:
the one you see on screen
the one you last saved
the one you saved before (as a backup)
Caution
When you dont
edit your file for at least double the time you specified for
automatic saving, all of the versions will have the same content
(your backup will be useless!). To avoid that, specify a longer
saving time or uncheck Automatic save.
