UltraISO is an application for Microsoft Windows for creating, modifying and converting ISO image files used for optical disc authoring, currently being produced by EZB Systems.
Contents
Initially UltraISO was shareware however since 2006 it has turned 'Premium' and become chargeable. The 'Free Trial' version is limited to ISO images of 300 MB or less.
Features
ISZ format
UltraISO uses a proprietary format known as ISZ. The format is 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 strengths. The file format specification is available publicly on EZB Systems's website. The format is now supported by third party applications such as Daemon Tools, Alcohol 120% and CDemu.
