People wonder, what is an ISO file, and what does the average person need with it? If you do much computing, chances are good that you'll run into ISO files eventually. Learn about ISO files so you know what to do with them the next time you run into them.
An ISO is a disc image.
What is an ISO file? In the simplest terms possible, an ISO is a disc image. ISO is a standard developed by the International Standards Organization for determining data storage on CDs. Basically, the ISO is one file that contains all of the raw data you'll find on a disc. Instead of storing information in separate files, the ISO carries all the raw data from every file. With the right ISO software, your computer can extract the raw data from ISO images to create files, folders and all of the directory hierarchy you're accustomed to seeing. However, ISO images themselves are just raw data.
What isn't an ISO image?
Not all types of files on discs work with ISO images. Audio files, for example, don't translate to ISO data because ISO does not support multiple tracks. Therefore, you can't have an ISO for a 10-track audio CD; it stores images differently. However, if you're dealing with multiple file types on a disc, such as a video game that contains both audio files and data files, you may still have ISO images for the raw data; just not for the audio files. Because the ISO file type does not support multiple tracks, it also doesn't work with VCDs, or some other CD types that use multiple tracks.
What do you do with ISO?
ISO images are typically the data you'd write to a disc. Your computer probably doesn't know what to do with ISO images. In order to use an ISO image, you need to work with it in a few different ways. You can burn an ISO image to a disc and access it like a standard CD. You can also use ISO software to access the data as if it is burned on a disc, even if it's not. Finally, you can use some compression software to view the data contained in ISO images, but not all compression software supports this functionality.
Different options in ISO software.
When working with ISO files, you have a few different options depending on how you want to manipulate it. To burn discs with ISO files, you can use most standard disc-authoring programs. Popular CD-burning software such as Nero, Easy CD Creator and others support burning ISO images.
If you want to use ISO software specifically designed to work with ISO files, you can still use it to create discs, but you can also use them to work with the file directly on your PC. Examples of ISO-specific software include: Ultra SO, ISO Maker and PowerISO.
When you don't need a disc and just want to view the file data and directory hierarchy, compression software can help. Compression programs including 7-Zip, WinRAR and BitZipper 2009 can typically open and manipulate ISO files.
 | If you need to burn ISO files to disc, it's really just a matter of finding the right software and finishing the job. However, make sure you're working with legal files, or you could be committing a crime. |
 | If you need to open ISO files, there's good news: you've got several different software options from which to choose so you can start working with the data quickly. |
