An ISO image or .iso file contains the disk image of an ISO 9660 file system. According to WIKIPEDIA, ISO 9660, also referred to as CDFS (Compact Disc File System) by some hardware and software providers, is a file system standard published by the International Organization for Standardization (ISO) for optical disc media (CD-ROMs and DVD-ROMs).

In Linux, it is possible to mount the ISO image  so that you can access the files without having to actually burn it to disk. Here is the simple way to show you mount and unmount ISO images without burning them.
1) You must login as a root user

$ su -

2) create a mount point

# mkdir /mnt/iso

3) To mount the ISO image file.iso to the mount point /mnt/iso, run the follwing command:-

# mount -o loop -t iso9660 /home/techkaki/file.iso /mnt/iso

or

# mount -o loop /home/techkaki/file.iso /mnt/iso

If you not specifying the “-t iso9660″ , it will work. The mount command is smart enough to work out that it’s a CD image.

4) Now you can verify that the ISO image is mounted 

# ls -l /mnt/iso

or

# df -hT
