Files created by tools from the Nero software package and using the NRG extension are exact copies of CD / DVD media, but the content may include folders with items required to mount images. “.Nrg” objects are processable and can be applied for the convenience of burning CDs. This is due to the preservation of the file structure necessary for the correct operation of CD / DVD / Blu-ray, which also allows the use of NRG elements for transferring information over the network and replacing physical media in the drive, for example, if game or software software requires the use of a disk.
