    In the usage how on earth do you specify to nrg2iso where the image file is.

  2. sgriggl says:

    go to the folder where it is located… your toolbar should show the location of the file – use the full extension in your command line.

    for example, if your image is on the desktop:

    nrg2iso /home/Computer/Desktop/image.nrg home/Computer/Desktop/image.iso

    Guys, you may just simply mount the .nrg file like an .iso file with or ‘mount -o loop -t iso9660 foo.nrg /mountpoint’

    I haven’t tried it yet but it should also work if you go to the directory first…

    (On the Desktop):
    cd /home/USERNAME/Desktop/ (Enter)

    nrg2iso image.nrg image.iso (Enter)

    Uh no, Guest you can’t simply mount it with that command. Wrong FS type. Thanks for the advice on nrg2iso. Works great

    This quite simply does not work. No matter what I enter, I get this:

    Nrg2Iso v0.4 by G. Kokanosky
    released under the GNU GPL v2 or later

    Usage :
    nrg2iso image.nrg image.iso

    –version display version number
    –help display this notice

    Any ideas?

    I received the message that it was already an ISO file. Changing extension from ‘.nrg’ to ‘.iso’ did the trick
