What is Disk image?
A '''disk image''' is a single computer file containing the complete contents of a device that contains data, such as a [[Hard disk|hard drive]], [[Tape drive|tape drives]], [[floppy disk]], [[Compact disc|CD]], [[DVD]], [[Blu-ray Disc|BD]], and [[USB flash drive|key drive]]. A disk image file (or simply a disk image) is an exact [[binary]] copy of an entire disk or drive. Disk image files contain all the data stored on the source drive including not only its files and folders but also its [[Boot sector|boot sectors]], [[File allocation table|file allocation tables]], volume attributes and any other system-specific data. A disk image is not a collection of files or folders but is an exact duplicate of the raw data of the original disk, sector by sector. {{tech-stub}} [[Category:Computing]]
