Since NRG files are generally CD/DVD copies created with Nero, you can double-click the file to open them in the Nero program if you have it. If not, this wikiHow shows you how to open NRG files by converting to a more popular format, like ISO. To open an NRG file, all you need to do is convert NRG to ISO, then mount the image.
