How to Super Compress Files

[assassin]

Hi,
Recently I have downloaded windows 64bit 6-in-1. It was tiny 9mb rar but when i extracted it it was about 3.49GB ISO . so can anybody tell me how this type of Compressing is done without using KGB software. i have also googled about it and it says something about "Huffman's algorithm" how to use it!!!!!!!!!!!

Without KGB archiver? Are you sure it worked? Did you mount it and install it?

[assassin]

Yes ! I have and i was wondering how such a compressing was done

[xje4bv]

You sure there's no padding or any hidden files? Unless there's repeated data, I'd say that a compression like this would mostly result in a corrupt file. I only know of UHARC. These file compression software only work well with Text files. EXE files are mostly already compressed to a certain extent.

Yes! i've checked it and there's no hidden files. and to check it i have installed it on virtual PC and it worked fine. But according to my research by using some Huffman's algorithm you can compress it.AND if ISO contains more ZERO'S it will compress like this. BUt i dont know how to do add more zeros in ISO. You can compress using KGB but compressing it take nearly hour's or even day's and it will take lots of RAM and processor

Oh please. I beg you. Please don't talk about that 64bit 6 in 1 files that you downloaded from rapidshare. I too downloaded it long before. It did boot fine and then blank. The file sizes in the ISO are intact. I think this has been discussed before in this forum.
Opened some of the big files inside the ISO image using notepad and hexedit. They contained scrambled data or sometimes they were blank ! Yet they showed perfect file size. That is a clear symptom of lossy compression.

Please refer to the following thread

UHARC offers high compression.

UPX compresses programs (Exe) to great extent but it does not create archives.

for this moment it's impossible...but in next 100yrs is plausible!

Even i have this veriosn.. it never installs.

Even if thid was possible, imagin how long it would take, like 2 years.

Winzip should be good compressing big files. You can get a 45 day trial of it
