Introduce to .ISZ format

All of you know .ISO formats as disk image file, today I’ll introduce you a new compressed .ISZ format.

Features:

  • Compressed format, you can even split into several parts.
  • Open, Burn, Mount on-the-fly as .ISO formats.
  • Password protection

And the specification of .ISZ file format is located here ( plain text ).

Currently, you can use UltraISO to compress ISO to ISZ, decompress ( maybe you don’t need to ), mount, burn…etc, from version 8.51.

Daemon-Tools now supports .ISZ mounting, from version 4.0.9.1.

An example:

I’ve made a VS2005 ISO (Intergrated With SP1), it’s about 4Giga large. After compressed to ISZ, the size reduced to half of previous: 2.1G.

However, the compress ratio depends on your content of image, it’s same as RAR or ZIP, no magic.

Enjoy it!
