ISZ (compressed ISO format) viewer for Mac OS X

Question

Is there any utility available that mount or view ISZ files (the compressed ISO format used by Ultra ISO) in Mac OS X?

Solution 1

If you're running Linux or OSX, this python script works great for me:

https://github.com/oserres/isz-tool/zipball/master

usuage

./oserres-isz-tool-1c8541e/isz-tool.py isz2iso try.isz
Extracting try.isz to try.iso -
Done

i was really surprised by the effectiveness of this compression:

-rw-r--r--   1 domdorn  staff   3,1G 10 Jan 18:06 try.iso
-rw-r--r--@  1 domdorn  staff   991M 10 Jan 18:04 try.isz

Solution 2

I have no experience with it, but AnyToISO claims to be able to convert an ISZ to ISO. From there you can mount or burn it normally.

According to Wikipedia, it uses bzip2 for compression. Maybe it's possible to use that command line program to convert it to a regular ISO?
