Super Compression Software

but what happens if that random number appears multiple times - isn't it possible to generate a "Legend Key" on the sequence of characters that the zip utility has found appears the most?

if "25.3573834594" appears 5 times, couldn't a header be added which states that [A1] = "25.3573834594" and replace every instance of that number in the file with an "[A1]" code everytime it appears?

This is done with multiple sequences that are the same.


will this work?:confused:

That is basically how these algorithms work. From your example, "25.3573834594" now appears 5 times, so it isn't so random any more, is it? So each instance can be replaced by something shorter.
 
I cant understand how a 100mb is compressed to 144kb with kgb.i compressed the nvida drivers.
Sorry explorer shows it as 144kb but properties shows it as 10mb.ahhh thats why.
err my mistake its still compressing..lol,,,never saw the icon in the system tray.

ok - a few good links came up when I googled "KGB Compress"

i'm gonna try it now too.
 
OK - i'm doing some extensive testing here, will post when it's done.

Score of Archiver Calculation: Megs Saved / Time Taken (secs) * 1000 ?
eg: 52 Megs Saved / 35 Secs * 1000 = Archive score of "1485 points"
(Almost like 3D Mark, heh...)

seem right to you guys?
 
Here's a Summary of the Results I got from different Zip Methods.

Files Zipped:
3 Mp3's: 59.2 MB
3 Videos: 62.6 MB
20 JPEG's: 37.8 MB
=============
Total Size: 159 MB


ZIP:
Compression: Best
Total Size: 139 MB (87.4% of Original Size)
Megs Saved: 20 MB
Total Time: 22 secs
CPU Usage: 52 % Average
Score: 909 Points

RAR:
Compression: Best

Megs Saved: 25 MB
Total Time: 26 minutes, 9 seconds

KGB: (Tried to compress 1 single 300kb JPEG) - Test Not Completed, and never will be.
Compression: Maximum
Total Size: ?
Megs Saved: ?
Total Time: 16 000 Hours and counting ??!!!
CPU Usage: Not much yet, but Virtual Memory Usage was insane!
Score: 0 Points

NOTE: Score is calculated by [Megs Saved] / [Time in Seconds] * 100

Sorry guys, but KGB is a waste of time...:(

That's for HTTP though. You won't find a program that compresses an AVI file you download at a ratio like that.

Other traffic can be compressed to....but the ISP would have to cooperate. I think the MWeb accelerator did that.

If you check the properties of a pppoe link then you'll see that lists compression % too. (0%:rolleyes:)
 
Why can't I download google web accelerator? Does it save bandwidth?
 
Keeper - run a test with 7-Zip as well.

You can set 7Z to an 'insane' mode as well, that takes much longer to compress, but returns better results. It's very scalable though, so you can change it depending on resources available.

Also remember, no matter how long your compression takes, your decompression is usually damn fast. That makes it pay off for people who distribute software to use the best method. If you download games via something like Steam, every bit counts. If valve can save an extra 1% of bandwidth on their side, it's a bargain, and you save on bandwidth costs as well.

For a home user, speed is more of a concern though :p

I'm actually quite surprised that you got that much compression out of AVI, MP3 and JPG. You don't state what codecs were used in the AVI, but most of those formats already use a form of lossy compression.
 
OK guys have been doing some tests today:

Office 97 (70.3mb)

Code: 
[U]Program Used[/U]     [U]Time[/U]            [U]Compression[/U]       [U]Result[/U]
WinUHA           2m58s           Best              70.0MB
WinRAR           32s             Best              70.1MB
Vista            8s              Built-in zip      70.1MB
KGB              1H13m42s        Good              68.7MB
Winzip 9sr1      12s             Best              70.1MB
WinACE           1m22s           Maximum           70.3MB  (LOL)     
7Zip             32s             Ultra             70.9MB  (LOL x2)


So Vista's built in Zip seems fine for me..

So we all agree KGB compress better that others but it's to slow?
What other programs have u guys tested and what result did u get??

Most shocking surprise for me was 7zip (latest stable version from their website), it
actaully increased the size..
I'd have to say Windows Built-in Zip and Winzip FTW!!!!
 
I think .zip is the best, overall.

on my tests it was blazing fast, and did quite well in compression ratio!
I used WinRAR to compress it to a ZIP, but it's the same I suppose.

However, when it comes to locking your files up in a password, rather use RAR than a ZIP. Zip is very easy to crack!

I saw loads of benchmarks on another site, and they said "NanoZip" does quite well in compression, and is speedy too! when I downloaded the beta though, it was dos based....damn.

so it's ZIP FTW from my side too.(Using winRAR)

Why not hide the Zip or Rar in a picture.. LOL :D:D (No one will even know it's a Zip) :D

I don't think Zip however supports "solid archives", like Rar and 7Zip does. Basically, Zip examines and compresses each file on it's own, even if there are several hundred files. Rar and 7Zip examines the several hundred files together and then compresses them.

To test this, take a single file and make twenty copies of it. Compress these with Zip, Rar and 7Zip and see the result.

Solid archives work especially well when you have a lot of similar files, like a whole directory full of HTML files.
 
I once used WinAce to compress the original Unreal Tournament install directory to about 130 odd megs, down from over 700 odd. This was way back, on the same P3 I'm posting from now, but with less ram back then.

I extracted Nero 7 from a UHARC archive a few years ago, 75+- mb into over 500mb. And it wasn't random data, it was a fully working version.

Lately I've been decompressing gaming mods off the cover of PCFormat dvd's, and I see they use Stuff It to make the archives. The one Unreal Tournament 2004 mod was 600 something compressed, and after decompression was around 1.8 gigs. That's about 2/3 ratio, which was pretty great. Slow to decompress, even on quad core, but worth it.

Honestly, if most files could just be compressed like that, then so much space would be saved. The net could become more efficient if more files or things were stored this way.

My 2c :)
 
ok the final verdict on my test for 100mb with kgb
latest nvidia drivers about 100mb
kgb only made it to 82mb and time 1hour and 26 minutes................is there something i am missing here..lol
 
i need to compress some avi files from a dvd to fit onto a 2gig card, i have done it before but it was a few years ago and cannot remember what i used.

what program can i use thats easy and fast?

Avi is compressed already...you won't get much compression whatever you use. I'd go for WinRar on max compression.

i don't understand how one movie cannot fit onto a 2 gig card when i used to have 6 movies on my 2gig mp4 player before.
