Once I heard of one super compression program, that could compress MS Office to just small 1,44'' floppy disk, but it was a scam. There is no such compression, maybe something which is a little close to it, but then the decompression of that file will take a few hours.
I just downloaded a 2 MB file which on extracting gives a 700 MB iso of windows vista. with your permission, can i post the link here ? its a 2 MB file. so u guys can check it out, n tell me how this happened?
Well its a DVD image that has an index of all the files that would amount to 700mb, but most of the files don't actually exist, though you might see the names in windows explorer. The user just clicks the setup file and gets a virus More likely than it actually truly being a valid full CD image.
The only kind of compression that is impressive (almost that impressive) is if it's pure text being compressed (since they can find a lot of similar bits to replace etc)
There was a man who once invented something like that (500mb into +/- 75/100mb) But he died and nobody ever found the code . (And nobody knows if it's true. Please don't say I am drinking or something, I read this on wikipedia a few months ago.)
ok ill post the file here, u guys just download it n see.. Its Windows vista 2 MB version... extracts to 700 MB believe it or not..
All of the files in the ZIP are corrupt and only contain blank lines. Change the extension of any of the files to .txt and open it in notepad. I guess you didn't manage to install it on your computer?
God knows how they made the file records record the wrong filesize, but that is indeed what they have done, every file is empty as nico said...... Did you really think you could squash 700mb by that much ??
It could be possible depending on the type of file. But you've also got to ask yourself just how efficient this would be - would you want to wait the extreme time for it to decompress? Maybe if it were a file that's not going to be used in a very long time. I recently started getting to grips with Unix via a cygwin port, I now use the tar and gzip for my compression, just yesterday I compressed a 1.4GB backup of my site down to 400Mb which I thought was quite reasonable. It only took less than five minutes to compress and the same to decompress so it would be Ok if I had to move the backup to another computer or re-upload to my site. H.
No it couldn't be possible for any type of file, it's an impossible ratio 99.965% compression is not achievable on any media by any of todays compression algorithms, it just isn't, we can get pretty close ...... http://www.maximumcompression.com/index.html http://www.maximumcompression.com/data/text.php
Guys, i know this is fake, just wanted to know how teh hell they managed to fake that ? The extracted file shows up as a 700 MB file in my windows explorer. freaky shit.. lol
Keep in mind rar has the capability to break files into chunks someone might have only given you one 2 meg chunk. Meaning it is possible that you are missing 700 / 2 (or 350) 2 meg rar files.
Or it actually is 700MB of whitespace! Don't know why he bothered but nico said he saw the files with just blank lines. Whitespace can be compressed that much
some files are extremely compressible (ones with spaces and 0's) - for example, check out the old DreamCast ISO's... They were about 30 megs and uncompressed to 600 or 700 megs! ARC was a strong compression if i remember correctly
