may be 1.5GB or so.
I have just one question to find solution
how they could compress 1.5 GB into 700MB.iso ?
The installation files inside the i386 folder in the CD are compressed with the MSCOMPRESS algorithm, that's why they fit in the disc and have an underscore instead of the last letter of their extension.Quote:

You are wanting to do the same thing with video. However, the video, when compressed will lose quality.
Windows isn't loading video onto the disc, they are loading data.
Got it?
Actually, that's his solution.Quote:

So it's impossible.
Compression works by using similar stuff to identify all the same things so compression of written words is the best. Imagine a novel written and inside the novel the word "and" "both" "murder" and "Jane Sparticus" appear hundreds of times throught the book. If the compression algorithm assigns the characters "1a" as and "2a" as both, 3a as "murder" and 4a as "Jane Sparticus" and then uses them to indicate where those longer names go, then you can imagine why text compresses so well. Other things like video do not compress well cause they're not text and every frame is slightly different.
As mentioned above, if you peruse an XP disk you'll see alot of Cab files or files with a _ at the extension which are also compressed (controlpanel._xe instead of controlpanel.exe) and those and cab files often compress written program files which use characters that can repeat just like a novel. In fortran programming for instance the words "for" and "if" or "then" are used repeatedly in writing fortan so they compress well into cab files.
