File Extension NRG
File extension NRG is generally used by Nero CD/DVD burning software to create and image of a disk to be burnt. Nero Burning ROM is a software application popular for authoring CDs and DVDs. NRG is created with ISO 9660 popularly known as the CD-ROM media. ?Data in an NRG file is stored in chucks containing a type id.
NRG version supports 32bit integers, but was change to 64bit integers with the introduction of version 2 nrg under Nero Burning ROM v5.5. Information stored in an NRG file contains header, chunks, DAO Information, CD-text, Extended Track Information, Session Information, Media Type and End of chain which indicates that there is no more chunk to read.
Applications such as Alcohol 120% and Daemon Tools can mount an NRG file as a virtual drive of a machine. This allows it to burn the file like normal Nero Burning ROM does.
The only threat this file extension can bring is copyright infringement. NRG file extensions are used to duplicate a file. This can be for backup purposes or reproduction for distribution.
A file containing an NRG extension can be converted into a standard ISO file through the use of NRG2ISO. Other software that can open and edit an NRG file include fusenrg, nrg4iso, PowerISO, IMGBURN, and others.
