An ISO is a digital media file that can be burned directly to a CD or DVD without any special encoding. An ISO usually cannot be played directly from the source file, but must be burned to a disk before it is able to be used. This article will cover the basic ISO procedures that relate to unpacking and burning digital media in the ISO format.
An ISO is used to transfer large applications and video formats and are also known as mirror images. For instance, if you wanted to create a backup of your favorite movie, but your DVD burner is at work, you can rip the DVD into and ISO and download the ISO to your work computer. You would then use an image burning software such as "ImgBurn" which will burn the ISO to a DVD which can be instantly played on any standard DVD player.
A DVD movie is not the only example of what an ISO file is good for. Large applications, video games, and much more can be transferred in the ISO format which makes it extremely easy to burn later with no conversion necessary. Because computer applications and DVD players use different encoders and codecs, they can be extremely complicated and difficult to copy a DVD without using the ISO format.
Since an ISO file is usually very large, it is usually broken into smaller parts and package with a zip or winrar program and sent in several pieces. Once all of the packages of the ISO are downloaded, the entire package is reassembled into the original ISO format.
Once the original ISO file is reconstructed, you can burn the ISO very easily by simply selecting "Burn Image File" on your recording software. It it is important to note that you must select the image option within your burning software when attempting to burn an ISO because burning a standard DVD will not result in the same file format.
Although burning and ISO is extremely easy, that technology is not meant to be abused and will not guarantee success when trying to burn copyrighted materials. Transferring files to ISO's and burning them does not bypass copyright protection mechanisms which may be encoded in the original DVD you ripped. This process should only be used for media that you own and have the legal right to make copies of.
