I have problem to mount a compressed (ISZ) image under Linux, which was created by e.g. UltraISO? I am aware about user-space fuseiso, but it fails to mount these images, as I have reported in Debian bugtracker (correct me if I ddi something wrong). I ask the community for a help: I need a proved solution to mount these images without decompressing them.
ISZ is a proprietary format, at the moment, it looks like there are no linux tools to support it.
daemon tools supports ISZ.
RE fuesiso - it can handle .ISO, .BIN, .MDF, .IMG and .NRG.
