A few day backs i went to my friends house i found out that he was a

 GTA SAN ANDREAS — CD

I was amazed how come a game of over 5 gb was compressed to 678mb

I reinstalled the game and found out the software name was  UHARC

I open the internet and starting surfing for downloading that piece of software i found a

little more information about that software from wikipaedia.

UHarc is a solid, high-compression 386+ DOS and Windows file archiver with multimedia support. It is written by Uwe Herklotz and is available in binary form

The software is ready to be downloaded here  http://www.filecompress.tk/

This software is must for all those whu want’s to compress large softwares and it is also great for backup
