What is ISO file?

Files with the .ISO extension contain optical disc images in an uncompressed form. A singular image with all files and disc’s structure of catalogues is stored in a single file, sector by sector – it contains file system of the optical drive.

Additional information

Data stored on any type of an optical disc (CD, DVD, or Blue-ray) can be archived as a digital ISO disc image. Disc images are created in order to simplify data transfer, in comparison with transferring it through a physical storage. An ISO image can be sent through a network, or carried using any type of removable data carrier.

The name of extension comes from the standardising document ISO 9660, regarding data storing format on CDs. ISO files can be used to emulate a drive with a CD, which helps to reduce physical wearing of the carriers, as well as of computer’s hardware. ISO format is often used to distribute within the Internet bootable disc images with system installers.

How to open ISO file?

ISO files can be mounted in the so-called virtual optical drives. Thus they can be used like physical discs mounted in a drive. All operating systems based on Unix offer possibility to mount ISO files in virtual drives. The situation is similar in case of Windows, since its 8th version. In previous versions of Windows, specific software was required for this purpose.

Structure of ISO files

It is worth mentioning, that ISO files have no standardised structure, despite such large interest and range of applications. Each ISO file can be different – they are exact copies of given optical discs.

When you install one of the applications from the list of programs that you found here, you should be able to open or edit the file with the ISO extension without any issue. However, if you still have problems with this, you may use the option of ISO file conversion to a different format.

We hope we helped you solve the problem with the ISO file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

There can be more reasons which determine that you are not able to open the ISO file (apart from the lack of the proper application installed).

First - the ISO file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the ISO file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the ISO file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the ISO file has not been completed and it cannot be opened properly).
