ISO Image Files is an archive file that contains everything that would be written to an optical disc, sector by sector, including the optical disc file system. It could store Blu-ray.
The name ISO was taken from the name of the file system used by optical media, which is usually ISO 9660. You can think of an ISO image as a complete copy of everything stored on a physical optical disc like CD, DVD, or Blu-ray disc—including the file system itself. They are a sector-by-sector copy of the disc, and no compression is used. The idea behind ISO images is that you can archive an exact digital copy of a disc, and then later use that image to burn a new disc. Most operating systems also allow you to mount an ISO image as a virtual disc, in which case all your apps treat it as if a real optical disc were inserted.
You should prepare source DVD disc, then insert a blank writable DVD into DVD drive; and you are supposed to make sure that your computer is well connected to the Internet as some DVD discs are encrypted. Then you need to connect the Internet to remove DVD copy protection and back up free DVD disc.
