File extension .ISO

File description

An ISO image file is a disk image made up of data contents for every written sector of an optical disc. This file system is usually used for CD-ROMs, DVDs, or Blu-Ray Discs. ISO images can also be burned onto a CD or DVD with the right software. These files are an exact copy of an existing system. The file name ISO comes from the file system used for CD-ROMs and DVDs, ISO 9660.

It is the most supported format for storing data on optical discs. There are three levels for storing specific data.
Level 1 is the length of the file: 8 character body and 3 character extension.
Level 2 can allow file names with up to 31 characters.
Level 3 allows fragmentation of files.

Description of the problem

If you have on your computer a .ISO file that you cannot open, you are in exactly the same situation as thousands of other people who have similar problems with this or any other unknown file.

There may be several reasons why you cannot open the file with .ISO extension. Directly on this website you can find a solution of the most common problem with the .ISO file – that you do not have on your computer the appropriate program to open the file.

Solution

From the list below, select the appropriate program, install it and double click on the icon of a file that did not want to open - the problem with the .ISO file extension should be solved. However, if this does not happen, go back to the website to learn about other possible causes of the error, which have been described at the bottom of the website.

Other possible reasons why your .ISO file does not want to open

In addition to the problem described above, i.e. the lack of the appropriate application to support the .ISO file, there may be several reasons that cause problems with opening and operation of the data format:

1. Incorrect version of the installed application

A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .ISO file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .ISO file, so download the update and check again.

2. Incorrect .ISO file association with the program

If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:

Right-click the .ISO file
Go to the "Open with" - then "Choose default program ..."
Locate the appropriate application
Click "OK"

3. The file is corrupt

It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
