Files with the .ISO extension contain optical disc images in an uncompressed form. A singular image with all files and disc’s structure of catalogues is stored in a single file, sector by sector – it contains file system of the optical drive.
Data stored on any type of an optical disc (CD, DVD, or Blue-ray) can be archived as a digital ISO disc image. Disc images are created in order to simplify data transfer, in comparison with transferring it through a physical storage. An ISO image can be sent through a network, or carried using any type of removable data carrier.
The name of extension comes from the standardising document ISO 9660, regarding data storing format on CDs. ISO files can be used to emulate a drive with a CD, which helps to reduce physical wearing of the carriers, as well as of computer’s hardware. ISO format is often used to distribute within the Internet bootable disc images with system installers.
ISO files can be mounted in the so-called virtual optical drives. Thus they can be used like physical discs mounted in a drive. All operating systems based on Unix offer possibility to mount ISO files in virtual drives. The situation is similar in case of Windows, since its 8th version. In previous versions of Windows, specific software was required for this purpose.
It is worth mentioning, that ISO files have no standardised structure, despite such large interest and range of applications. Each ISO file can be different – they are exact copies of given optical discs.
