[edit] ISZ format

UltraISO uses a proprietary format known as ISZ. The format advertised as "ISO Zipped" even though it is not a simple zip archive. The format uses ZLIB or BZIP2 to compress the data, and can support AES encryption of various strength. The file format specification is available publicly on EZB Systems's website.^[1] The format is now supported by third party applications such as Daemon Tools.
