I can't see why yo8u'd ever want to do this?

Sent this to another list, but no one had any ideas, so thought I'll try
here. Please find below.

Subject: extracting DMG files

> Hi All,
> So, I found out, that 7zip can extract DMG files. For now, I'll assume
people know what DMG files are. If anyone knows the answer to this one, they
certainly will, anyway. So, I thought I'd put this to test. It extracted the
Mac version of java platform, no problem. But, the DMG files, that I wanted
to extract originally, which have came from an IPSW file (again, will assume
people know what they are) 7zip gave errors to, saying it can't extract. So
I found DMG extracter, which, was totally inaccessible. Narrator sort of
read the things, but they weren't clickable. Searching some more, I came
across HFSEXPLORER, which is an application, designed to extract DMGS, and
what else not. Although, when trying to run, this told me that I needed java
platform, before it could work. So I installed that. Now, This is
accessible, I checked so that this opens DMGS by default, and everything.
NOW, here's the issue. The 2 small IOS DMGS are actually not supported,
apparently. And, the third, the 1.8 gigs one, it was apparently reading
incrypted disk image, but didn't beep, give progress, or anything. So after
an hour, I presumed that it just doesn't work. So now the question. Anyone
had luck extracting DMG files, from IPSW files? As in, after unzipping the
IPSW, and then trying to extract the DMGS, found within? BTW, DMG is
identical to ISO on windows, and IPSW is what contains apple's IOS upgrades,
when downloading it off line. Just thought I'd clarify, for those that are
interested in a few words.
