The file you downloaded is *.nrg.zip is a Nero disk image of the appropriate .iso file. An .iso file is just an exact disk image of a cd or dvd. I use a program called Daemon tools to mount .iso files like the Ford Cd ones so I do not need to burn the images to DVD or CD media. This program can be found at this link and is easy to install and use.

The only requirement for this is that you need to download the .ISO files to use this software. feel free to message me with questions. I am looking at downloading all these images and submitting them to torrent again. Will update you as I update each image.
