Hi all,

This may seems to be a foolish questions. I have windows 7 installed in my computer. There is a windows7 image file .nrg in my hard drive.

But i am not sure whether this is the image file i used to install windows 7 on my computer.

I want to find whether this is the same image file i used to install my current windows installation. how to find that without write the file into a dvd or installing it in a virtual machine.

I can manage without knowing this, but i guess it will be interesting to know.

Hello, and welcome to Geeks to go !

Not sure if this will totally answer your question, but some information never the less.
A .nrg file is a proprietary CD image file format used by Nero Burning ROM, a utility suite made by Nero AG, to create and burn ISO 9660 CD images.

Other than Nero Burning ROM, a variety of software titles can use these image files. For example, Power ISO, Alcohol 120%, or Daemon Tools can mount NRG files onto virtual drives for reading.

Contrary to popular belief, .nrg files are not ISO images with .nrg extension and a header attached. For technical details on the nrg format, see below.
