How to convert nrg image to iso image

How to convert nrg image to iso image

Before going in detail about this article, i want you to know about NRG and ISO files. If you know about these, you can skip the first section of the article and read the conversion part.

DISK Image:

DISK image is a kind of archive files which collects all the files of a  CD, DVD or storage media in the original structure. It is created by creating a complete sector-by-sector copy of the source medium and thereby perfectly replicating the structure and contents of a storage device.

These are the main 2 formats which we generally see in our daily work

NRG Image Format:

NRG is the image format for CD/DVD image format used by NERO Burning Rom to burn a CD/DVD. Intially this format was only supported by NERO but some other tools now support this file format. These kind of disk images are created by NERO. 

ISO image Format:

It is the standard disk image format by ISO (International Organization for Standardization). It is supported by all available CD/DVD burning tools.

Many image burning software only support iso image extension, but what if you have an image file with nrg extension. I have a good solution for that. There are many software tools which easily convert nrg files to iso files in some simple steps.


Follow these steps

1. Download  convert3iso from the given link

http://www.paehl-info.de/cdr/convert2iso.zip

2. Choose NRG to ISO in the Option
3. Select source iso file
4. define target path and then click on convert.

Now you will have an ISO disk image converted from NRG disk image.

If you have NERO and use it to create disk images, I will suggest you to create ISO disk images. By default it burns NRG disk image but also have an option for ISO. That will reduce the conversion step.
