Images

• A disk image is a file that contains an exact copy of an entire disk or drive. An image contains more than the files you normally see when using a drive or disk; it contains every sector of information on hard drive.
  
  

Importance

• Because image files contain all of a drive's information, they are commonly used as backup files.
