I can show an 8GB file compressed to 10MB (see the 8GB image file at http://legacyschool.us.to/nookdev/clockwork/0.1-ext4/ )
And that's plain old gzip.
many website claim that they have compressed 6 gb or more large game files to a very small size of 1 or 2 mb or even less using kgb archiever but realythey work.also they are compressed file so they may contain viruses and other spyware.i personally download some of the games from rapidshare and warez site but they don't work although they took more than 9 hours to decompress.is they realy work ?or these websites are doing this to increase their rapid points because lower the file size,maximum will download.
so if anybody come acrosss these ,discuss about it,
also be careful using these files
