What are ISZ files and how to open them

Are you having problems opening an ISZ file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is an ISZ file?

An .ISZ file is an ISO Zipped file.

Files that contain the .isz file extension normally store compressed disk image files. ISZ files are very similar in nature to ISO files, but the contents of an ISZ file are compressed in order to make the file smaller and save disk space.

The ISZ file format also supports password protection and encryption. Huge ISZ files may be split into separate volumes. The smaller file sizes of the split archive make it easier for users to distribute the files over the Internet. The ISZ file format was created by EZB Systems, the same software company that created the UltraISO software application.
