unbelieveable. Razz if u still don't believe me, extract it and see if it takes 1gb! Twisted Evil

1 GB worth of data within a rar file totaling to 70 KB?! wow, that's some pretty serious compression. That could only be done with text files and the like, it could not be done with video and music like that right now. Perhaps, though, in the near future. I dloaded it and extracted it, and yup, it takes 1 GB. That's crazy.

What does it contain?

it's unbelievable!!!!

how can i make a 1 gb to 70 kb ??!?
Donutey
once again.. what does it contain, it would be relatively easy to do this just have a small text file duplicated how many ever thousand times, then rar compresses it into one file with the compression routines telling it to multiply it by x amount whenever it's uncompressed...

It is possible to have files which mimic a certain size, which is how miniISOs work. Usually those are about 3mb, but when mounted represent a CD of e.g. 650mb. Quite how it works i'm not sure, but I sense some trickery involved in this article.

Wow, thats some compression.

Is there any explenation on how he did it?

I really wish i can do it to all my files
Donutey
and... once again it's a trick... there's no way to compress usable data that much...
izcool
Haha, hilarious. Laughing

lol. you're the closest. Razz

of course ther'es a trick guys.
okay. the .txt file in the archive is a DUMMY text file. there's nothing in it. not a single character. but still it takes 1gb space when you extract.

what you do is, use a DOS command to create the dummy file, wtih any extension, any file size u specify..

so what's the command? Evil or Very Mad

google and find out. Twisted Evil lol.

well this was really great trick.Though I have just read this and didn't search google for the command but hoping I will see the command soon here. Smile

Very clever...

I suppose it is be entirely possible...

Yet I am surprised that I can not work out how you did it...

My best guess is that the .rar file is corrupt, I wonder if it would still look like 70kb once compressed if you put it into a WinZip (.zip) file.

The empty .txt file created from MS-DOS part still puzzles me...

Oh well, it won't be long till someone posts the DOS command or banglamusic releases his mighty secret.

Whatever...
If the file is all repeating characters, like XXXXXXXXXX, then it could compress down to like 20 bytes. It all depends on the data.

Its all bull shit stuff and aint dwling it for security reasons.

Once one of my forum members gave me a file link on chat saying it was 750 Mb of Longhorn in just under 1 MB, and just by curiosity i dwled it and just to find it shows the Vista setup screen & my PC a bit screwed up.

Yes the folder did show its size a 750 MB on unpacking but there was nothing in it. maybe some way to fool windows abt its size

Also some one from a tech forum said that a viedo file of over 30 minutes was recorded with a file size of less than 50 KB. It had a very high commpression but sadly it cant be run on a PC or any other damn device. And same for other files. They can be commpressed but will be rendered useless

I suppose compression rate is due to the different file formats, it might compress 70% for this format or type of file, but not all of them.

Yeah, I notice that with WinZip, it compresses files like big .txt files more than other files e.g. .exe files that are the same size before compressing.

So if I got a 10mb txt file and a 10mb .exe file and compresses them, it would compress them as small as it can while making sure that it can be uncompressed without corrupting the data. So in the end, it would compress the txt file say 86% (depending what is in it) and the .exe file would not be as compressed because the kind of file is more advanced.

It also would depend on which program you use.
win66
unbelievable. Can anyone tell us how to do it?

Whew...WordPad can open it... takes abt 15 minutes..
ocalhoun
It's easy to get extremely high compression ratios!
Try one of these:
Compress a video avi file in which every frame is identical.
Compress a wav file that does not vary much into a mp3.
Compress a text file that contians the same charachter repeated Millions of times.
It all depends on the type of data, and knowing how the compression routine works.

This is a great find...
Thanks for the info....

It's a hoax.Do not grill your brain about this question.you can't shrink a 1GB complete movie file into 70kb.So Dream on.

If you want better compression than RAR you'll use:

It's not a hoax or a dream. Redundant data compresses well. Fill a text file with the letter a 50,000 times. It will compress MUCH better than mashing 50,000 keys in instead.

edit:

I compressed TWICE as much information into LESS THAN double 70kB
