ISZ file is a compressed disk image file. The format was created by EZB Systems. ISZ format is nothing more than a compressed ISO image.
ISZ format follows closely the ISO format standard, and uses compression to achieve smaller file sizes that help to save disk space. ISZ format uses ZLIB and BZIP2 compression methods, a lossless compression algorithms that retain file metadata. ISZ format also offers password protection and encryption: AES128, AES192 or AES256 (128-bit, 192-bit and 256-bit key encryption, respectively).
Large ISZ files can be split into smaller parts. Each such part retains name of the original file, but starting from second part the extension is different – first part has ISZ extension, second i01, third i02, and so forth. Splitting files into smaller fragments allow users to store data on multiple storage devices and combine the parts into the original files when needed.
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 ISZ extension without any issue. However, if you still have problems with this, you may use the option of ISZ file conversion to a different format.
We hope we helped you solve the problem with the ISZ 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.
There can be more reasons which determine that you are not able to open the ISZ file (apart from the lack of the proper application installed).
First - the ISZ 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 ISZ 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 ISZ 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 ISZ file has not been completed and it cannot be opened properly).
