from this screenshot, its proof that even Vista installation folder can be compressed up until 3%...
there's even another 2 screenshot of 0% (700M+B original into 2MB+ .rar file) and another one 8%


an 8% compression?


this one is 3%


can u believe it says 0%?

so anyone knows how to do this?
either using Winrar, or Winzip, or KGB archive..

able to extract ?

yah.. takes quite some time to extract. but i wana know HOWTO?

Some file cannot be compressed than much such as those downloaded from the internet: mp3,movie file because it is already compressed.

If you compress word, excel file then a lot.

yah.. thank you captain obvious..

i just want to know HOW TO do that..
cause what i've downloaded is files that surely cannot be compress that much..
the files are windows vista installer files, another is game files...

if text files, i can surely do it to a whooping 30% without any trick..

ever heard of KGB Archiever?
currently it's the best compressor.... but not to that extent!

Proof? *snorts*

yes in english dictionary.com it says "evidence sufficient to establish a thing as true, or to produce belief in its truth." - http://dictionary.reference.com/browse/proof

It's possible to compress all those gigabytes of data to up to 3%, BUT, you're not guaranteed that extracted data will work, if the file has digital signature, it'll corrupted, and in many cases, those files are empty files with lots of spaces. Not to mention that compress/decompress operation could take ages if using old hardwar. In the end, it's just not worth your time and efforts, just use either RAR, 7z or UHA for best compression (no ZIP pls)...

I've done it before with KGB Archiver. I've also managed to extract the archived/compressed file done by KGB. However, this will increase the risk of file failures. It took me 3 days to archive/compress my original Vista Ultimate disc (Non-SP1) on a P4 3.0GHz, 1GB RAM.

does UHA compression is better?

UHA compression is mainly for game files such as DDS or graphic files, as always there's no way to truly compress a multimedia files such as mp3 or ogg or equivalent files...

Agreed, no point compressing MP3 because they're, a type of files that've been compressed.

If one need to compress mp3 files, the only option is to re-encode the files to lower bitrate, but then they'll lose the quality even if the lowered bitrate-files are encoded back to higher bitrate...

well, what im trying to compress is snatllation files. for games. since games nowadays are huge in term of their installation files, i wanna transfer it to my friends using smaller media such as thumbdrives and cds (not dvds)...

that's wasn't quite possible, depending on the game tough. Game nowday includes high resolutions textures and models and such files won't compress nicely unless you know how to rip yer games. Why don't get a 8gb thumbdrive? It's sufficient for almost newer games... but in the end, it's unethical to copy and share games with others unless you sell it to them (or they have the appropriate licenses)...

Your compression test is highly inaccure. next time you do it, be sure to use the same test file and dictionary size

seriously, i don't think that level of compression is possible for games, etc.

Precisely. Besides, most MP3 songs (English) aren't more than 10MB.

It's illegal to transfer copyrighted games. Like "FarCry3r" said, get a 8GB thumbdrive, it's quite cheap and should fit the latest games. Try KGB Archiver like I recommend.

Seriously, it is possible, I've tried it with KGB Archiver but it took me 3 days to compress 2GB into 2MB on an Intel P4 3.0GHz and 1GB DDR RAM.

yah, it's possible, but the uncompressed files will lose digital certificates if one need them, such as Microsoft Office 2007, try it and you'll see what I mean...

I've compressed my Microsoft Office '07 with KGB Archiver to 2MB and I've also managed to extract it without problems. Heck I even used it to install on another computer but with a genuine serial (of course).

my last few attempts with Office 2007 failed with MSORUN.DLL digital signature was invalid... hmmm, what could have been wrong here eh?

Here's how I did it:
I made an ISO of Microsoft Office '07 with MagicISO.
I archived the ISO with KGB Archiver at full compression.
I extracted the archive on another computer.
I mounted the ISO on that computer.
I installed the ISO on that computer.
It worked.

Dang, ISO is teh key, I compress the files as it is, no ISO medium, that's why the digital signature was corrupted...

Precisely, hope my solution works for you. May I know how long it takes to compress?

ARE YOU SURE!? Can anyone prove that what TechnoDude94 is saying is true?

Maybe you can send me that 2mb Office 07'? I can PM you my email, you attach that file to me! I want to see if I can extract!!

(I have no patience to wait days to compress Office 07' ler)

Dang again, compressing MSO 07 within ISO container is like, 3 days? and after 50% of compressing, I only managed to get 95.5% compression ratio! wtf? compressing without ISO container gives me 4.x% compression ratio and it still need around 3 hours before completed. Never could get 2% ratio even when I select the smallest compression...

3 days? thats looong man...

What about the decompression speed? Is it fast?

Decompression speed is as long as compression time, depending on your hardware, if just use old P4 and 512mb RAM, it gonna take ages! dual/quad core is recommended...
