What is ISZ file?

The file in the ISZ format belongs to the Disk Image Files category. The author of this format is EZB Systems. In addition to this file, the Disk Image Files category includes 203 related files. Zipped ISO Disk Image appears on 1 operating systems as a functional file. The file will work on Windows systems, unfortunately not on others. The UltraISO application is recommended to open the file. It was released by EZB Systems, Inc.. Alternatively, you can use 5 other programs. DAEMON Tools, Alcohol 120%, WinMount, Astroburn will apply when it is not possible to use UltraISO.

How to open ISZ file?

The main problem with Zipped ISO Disk Image is that the ISZ file is incorrectly associated with programs. This causes the file ISZ to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the ISZ file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install UltraISO

An often overlooked issue is to make sure that UltraISO is installed on the computer. This can be achieved by typing UltraISO into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support ISZ files.

Step 2. Create association of UltraISO with ISZ files

If, despite the installed application, the ISZ file does not start in the UltraISO application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the ISZ file with the UltraISO program.

Step 3. Update UltraISO to the latest version

If, however, after binding UltraISO with Zipped ISO Disk Image there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the EZB Systems, Inc. website and install the latest version.

Step 4. Check for the following problems with the ISZ file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the ISZ file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our ISZ file. However, remember that not every infected ISZ file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the ISZ files changes over time. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair ISZ file corruption. You can restore the file from a backup or use EZB Systems help.
The program can also signal the fact of encryption. The encrypted ISZ files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. Copying the ISZ file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the ISZ file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the ISZ file for a certain period of time. If the problem persists, restart the machine.
