Preventive Maintenance
Preventive maintenance is essential for keeping your computer in
good working condition. A few basic tasks include:
■ Creating backup files
■ Deleting unwanted files
■ Optimizing your hard drive
■ Running virus scan software
It is recommended that you backup files and optimize your hard drive
at least monthly. If you use your computer a great deal, you may want
to perform any and all of these tasks more frequently.
Cleaning Up the Hard Drive
As you use your computer and store files, the hard drive begins to fill
up, get cluttered, and ultimately affects performance. To prevent this,
you can delete files that you are not using.

CAUTION: You should not delete any unfamiliar files. If in doubt, do not
delete.
