Learning the Basics
Saving your work
Saving your work
Before you turn off the computer using the Shut down command, 
save your work on the internal storage drive, external media, flash 
media, or optical disc. This is one of the most important rules of 
computing.
Many applications offer a feature that saves documents at regular 
intervals. Check your program’s documentation to see if it has an 
automatic save feature.
Backing up your work
Back up all the files you create in case something happens to your 
computer. You can back up your files to different types of media 
such as CDs, DVDs, external storage media, or to a network, if 
available.
To back up several files at one time, use the Microsoft
®
 Windows
®
 
file recovery program preinstalled on the computer’s internal 
storage drive. Also see 
.
HINT: Backing up all the files on your internal storage drive may take 
a considerable amount of time and multiple CDs/DVDs. You may 
prefer to use a high-capacity file recovery system, such as an 
external hard drive.
Using the optical disc drive
Optical storage is a popular medium for software, music, and video. 
Digital versatile discs or Blu-ray™ Discs provide a significant 
increase in data storage and support features that were not available 
on previous video platforms. These features include wide-screen 
movies, multiple language tracks, digital surround sound, multiple 
camera angles, and interactive menus.
TECHNICAL NOTE: Your optical disc drive is set to play region 1 
(North America) for DVD-ROMs or BD-ROMs, depending on the type 
of drive. If you play a DVD or Blu-ray Disc™ from another region, the 
drive will automatically change to play in the format of the other 
region. The drive will allow you to change regions four times. On the 
fourth change, the region will be “locked in.” That is, the drive will 
only play DVDs and Blu-ray™ Discs from that last region. Note that 
changing from region 1 to region 2 and back to region 1 is counted 
as two changes.
