An ISO file Image or Disk Image is a file that contains all the data contents of an optical disk (CD, DVD or Blu-ray disk). This file contains also the file system of the optical disk and can be created by using a burning software like Nero, ImgBurn, etc. The advantages is that you can always have the digital copy of your original optical disk inside your hard drive or removable media, without the need to have the physical optical disk.
One of my favorites freeware utilities to mount an ISO file is called "Virtual CloneDrive" by "Slysoft" company. Using this utility you can mount .ISO, .CCD, .DVD, .IMG, .UDF and .BIN files very easily.
