What is ISO file?

The extension .ISO refers to files of the type, ISO disk images. These are the exact copies of data present on a CD or DVD. The file is also capable of storing the exact structure of file system information.

These ISO files are usually used for backup purposes to store the data present on vital DVD and CD resources. One particular case where ISO files are used is also seen where the PCs don't have a physical CD or DVD drive present to read the disk data. Hence a Soft-copy version such as the ISO copy of the disk is used in such cases.

Program(s) that can open the .ISO file


If you cannot open the ISO file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable application that supports ISO among those that are installed on your computer.

A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the ISO file can be found below. Now just download and install the appropriate application.

This site also defines other possible causes causing the problems with ISO files.

Possible problems with the files that are in the ISO format

The inability to open and operate the ISO file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the CD/DVD/HD DVD/Blu-ray Disc ISO Binary Image Format file. Below is a list of possible problems.

  • Corruption of a ISO file which is being opened
  • Incorrect links to the ISO file in registry entries.
  • Accidental deletion of the description of the ISO from the Windows registry
  • Incomplete installation of an application that supports the ISO format
  • The ISO file which is being opened is infected with an undesirable malware.
  • The computer does not have enough hardware resources to cope with the opening of the ISO file.
  • Drivers of equipment used by the computer to open a ISO file are out of date.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the ISO file should operate with your programs without any problem. If the problem with the ISO file has not been solved, it may be due to the fact that in this case there is also another rare problem with the ISO file. In this case, the only you can do is to ask for assistance of a professional staff.

From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK.

Is there a universal way to open unknown files?

Many files contain data in the form of text or numbers. It is possible that while opening unknown files (e.g. ISO) a popular Windows simple text editor, which is Notebook will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
