UltraISO
About UltraISO
UltraISO is an application for Microsoft Windows for creating, modifying and converting ISO image files used for optical disc authoring. Since the first release of UltraISO on 20 April 2002, its author EZB Systems has maintained and kept the product shareware.
UltraISO is currently produced by EZB Systems.
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.[2] The format is now supported by third party applications such as Daemon Tools and Alcohol 120%.
