CYBER-DUDE

It is a compression tool called
KGB Archiver.
I compressed my game Crysis 3
which is 8.50 GB into 90MB!!!!
It is an open source
compression tool like Alzip and
winrar but the compression
rate is much better then any
other compression tool. It uses
AES-256 encryption to encrypt
archives . The disappointing
thing with KGB Archiver is due
to its high compression rate its
minimum
hardware requirements is
high (Recommend processor
with 1.5 GHz and 1GB RAM)
and compression and
decompression process is time
consuming.
Strength: -
Very high compression power
with very accurate result and no
loss of data.
Weakness: -
Due to high compression rate,
the time requires to compress
and decompress the file is high.
