how to compress gb to mb

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
consumin
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.
