NRG files usually represent a copy of a CD or DVD made with the Nero program. If you have Nero installed on your computer, you can open an NRG file by simply double clicking on the corresponding icon. If not, this article explains how to open an NRG file by converting it to a more popular format, for example the ISO format. In order to use an ISO file, it must first be "mounted" to your computer using a virtual optical drive.
