I've not noticed any threads about the latest Omega drivers. They seem
stable enough but don't make much of a difference for me (no problems
before and no problems after, so I shouldn't grumble). The update
seems to be aimed at fixing problems with other people's cards
(mobility Radeons etc.)

Why the heck are they in CAB file format?

Apparently to keep the size down. Some of the download mirrors can be
notoriously slow and many people are still on dialup.

Will CAB is a compression format standardly inbuild in windows. And
the cab is 16-17Mb while the EXE once extracted is 19Mb ...so it does
work!

I just compressed the exe into zip and rar to see the difference.
zip=18.6mb
rar=16.8mb
cab=16.8mb

Considering that everyone has .cab file support built into windows
it's surprising that more people don't use .cab.
 
Throw in the .ace 2.0 format :)

As for .cab, it is owned by microsoft. I think that's got to do with not
much distributions.

Lets Try Uharc
ALZ:3 ( maximum but oh so ... long wait ) = 16.8Mb ... well I guess
that proves that the EXE file can downsized unto about 16.8mb

Ya know, all those compression tools use different algoritms and work
better on different kind of files. Uharc for instance is great for
compression certain media and ..indeed for Games and alike...

I got hold of an office 2003 disk (copy) that has every office application
on the one CD, extracting isn't successful as many files fail to copy, but
when you have most of the files on the hdd, it amounts to 1.5gig from a
650mb disk, you can view the files and install correctly, so what kind of
compression is used here? its invisible compression that acts on the fly as
you use the files...

You did use that option "leave installation files on disk" in that
case most of the 650Mb of the CD stays as copy on your harddisk for
when office needs a function, so it's 1500Mb - 650Mb = 950Mb for
office installation...

That brings back things in reference!

no-no, this was a pirate copy with all office 2003 applications jammed onto
one disk, I attempted to copy it again for another friend, but no program
would touch it, I manually dragged all the files onto my hard drive to drag
back to a new disk, that failed too, but what I did retrieve was 1.5gig (off
a 650mb cd) UltraISO managed to make a perfect iso and burn it mind you, but
still, what kind of active compression could be at work here that makes
identical files half there size without having to archive them?

Linux Knoppix does better than that. It has about 2.8gb of data
compressed onto one cd. I don't know what compression technique they
use though.

that's right, I have that version of Linux too, it was a bugger to copy
because I attempted to extract the iso to add my own manual to it. only
UltraISO allowed me to open the iso, add to it and burn it to disk.

Depends on the type of file, I am sure some library files and alike
are very easy compressable to a high extend, while the EXE files might
just do 95% as max....
 
I don't think it's the compression at all.
Compression comes into play everytime you DECOMPRESS the archieve on your
harddrive. Not when copying to a cd.

Quoting Highlandish: "I manually dragged all the files onto my hard drive to

A 300mb file is compressed with zip, and it's compresssed size is 100mb. Now
when you copy this 100mb zip file to other pc, it should take up moreless
100mb, unless you unzip it.

You are saying there was actually 1,5GB worth of data on a 650mb cd? That's
not possible. It's a cheap cd-protection known as DummyFiles.

that is possible that it was dummyfiles if it was a legit program on an
original cd, but consider that this was a compilation of all MS office
products put together by a hacker for pirating purposes, also consider the
knoppix Linux distro, both cd's, when the contents are dragged off the cd,
take more space on a hard drive than on the cd. sure there are cab files
amongst these files, but no compressed archive of any kind have been
actively selected and decompressed in the drag and drop process. all I was
asking is can there be a compression technique that can compress files onto
a disk like these 2 (and possibly more?)

and I do realise that in the process of making an iso file, you can compress
the contents to make the iso a compressed archive its self, and then burn
that iso to disk at that size. perhaps this is the method used.

Yes, it is. Go get Knoppix and install to your HDD. There is about
2.8gb of data on that one cd.

that's not exactly what I am saying, sure there are compressed archives on
the knoppix disk that extract on installation, I am talking about drag and
drop size when files are taken off the cd onto the hdd.

OK, got you. You're right, that would be impossible.

Don't even need to drag/drop.
open the CD, select all files, select properties: file size shows as
over a gig
