Loading ISO image files
Create a directory as a mount point:
sudo mkdir–p/mnt/iso
Use the following mount (assuming your ISO image file is named Disk1.iso):
sudo mount-o loop disk1.iso/mnt/iso
So you can mount your ISO image files under the/mnt/iso/folder.
Loading NRG Mirror Files
NRG is actually a iso9660 image plus a fixed-length file header, so you can add the offset parameter to the mount:
Create a directory as a mount point:
sudo mkdir–p/mnt/nrg
Use the Mount command as follows:
sudo mount-o loop,offset=307200 image.nrg/mnt/nrg
