text: i want to retreive a file with the extension *.nrg? i have a cd image with the extension of *.nrg. i have nero 7 but i dont know how to retrive the informations from it??? without a cd-writer the only option is to convert or extract. since you have nero, create a virtual drive and mount the file on that, and then extract the files of the virtual drive.   or else there are two application's that can help are:  1) http://www.isobuster.com/ 2) http://www.magiciso.com/  both offer trial version's, it should be enough.  good luck.
