Administrator DKT27 Posted January 8, 2011 Administrator Share Posted January 8, 2011 It's not fake. Quite possible. Check out KGB Archiver. KGB Archiver has been known to compress 10GB into 100MB. But that would take 5 days on Xeon processor and 2 days to uncompress. ;) Link to comment Share on other sites More sharing options...

KGB Archiver has high compression rates.Too bad, the project is unmaintained...7-Zip has good compression rates if you choose the correct one...++ Link to comment Share on other sites More sharing options...

shajt Posted January 8, 2011 Share Posted January 8, 2011 Dear shajtThat is fake in some case.It seems so , just thought that it was hard to achieve.How long it took you to extract it ? Link to comment Share on other sites More sharing options...
jalaffa Posted January 8, 2011 Share Posted January 8, 2011 That's probably fake.I'm with you. There is no magical archiver able to compress normal stuff so much better than others. Link to comment Share on other sites More sharing options...
mara- Posted January 8, 2011 Share Posted January 8, 2011 It's fake for sure. Shought, there is no way it can compress 10GB to 100MB, no way! It's possible they have the best compression, but there is no way to compress such big data to such small data.Cheers ;) Link to comment Share on other sites More sharing options...

Few years ago I had downloaded a game of 1.2GB compressed into 10.1MB. Took many hours to decompress, but I'm 100% sure about it. Not only that, implague, a member here, compresses his ISO files into such a small size regularly with KGB. Link to comment Share on other sites More sharing options...
LeetPirate Posted January 8, 2011 Share Posted January 8, 2011 A massive file with redundant sequences of similar hex code can compress into insanely tiny files. Like for instance game images that they copy just the securom part can zip to 4MB but when you unzip it you end up with 4GB because the rest of the file is just zero filled for padding.A file with real data can never reach that compression ratio, regardless of what tools you use.

Administrator DKT27 Posted January 8, 2011 Administrator Share Posted January 8, 2011 Check out the PAQ method of compression yourself. I'll compress Hirens BootCD with KGB in couple of weeks and will show that it is possible. I do not guarantee the Windows 7 file is safe or not, but it's not impossible. I've done it myself in the past, a 1.1GB game, a graphic adventure, into 10.1MB. Link to comment Share on other sites More sharing options...
mara- Posted January 8, 2011 Share Posted January 8, 2011 Sorry DKT. :rolleyes: Well, it's still hard to believe in that. I tried few times to compress something, but when I sow how much time it takes, I just gave up.CHeers ;) Link to comment Share on other sites More sharing options...
