Nero is definitely not my choice of disk compilation utility, however, it is without a doubt one of the most popular disc burning software and therefore you might land-up on some disc-image file compiled in "Nero Image" format (.nrg file). Thankfully, .nrg files can be easily converted to standard .ISO file-format which is supported by all disc burning utilities, nrg2iso does exactly that by converting Nero CD images to ISO-9660 CD images with a single click almost instantly.
