Or just use a tool like WinRAR,which can read from the ISO file as if it were a zip file or something
Daemon tools will also be able to emulate the ISO as if it were a drive in your system.
Oh and btw, you have not mentioned your OS, the above information is for windows, on linux, use the "mount -o loop xyz.iso /mnt/cdrom" to mount the ISO on /mnt/cdrom.
