ISZ file format is a type of archive file format with capability of compression. This file format is similar to ISO file format with one advantage of less file size.
A number of applications use this file format to store a number of different files. The ISZ file format stores files of various formats in one single file and then compresses the file to reduce the overall disk space required by that single file. Encryption and password protection is also supported by this format. In case the file to be archived is too big, then it can be split into several parts having ISZ format for easy sharing.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .ISZ file, there may be several reasons that cause problems with opening and operation of the data format:
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 .ISZ file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .ISZ file, so download the update and check again.
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:
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.
There may be several reasons why you cannot open the file with .ISZ extension. Directly on this website you can find a solution of the most common problem with the .ISZ file – that you do not have on your computer the appropriate program to open the file.
