  KGB Archiver is a discontinued file archiver and data compression utility that employs the PAQ6 compression algorithm. Written in Visual C++ by Tomasz Pawlak, KGB Archiver is designed to achieve a very high compression ratio. It has ten levels of compression, from very weak to maximum. However, at higher compression levels, the time required to compress a file increases significantly. As a consequence, the program uses memory and CPU intensively.
  
  KGB Archiver is free and open-source, released under the terms of the GNU General Public License. Version 2 beta 2 is available for Microsoft Windows and a command-line version of KGB Archiver 1.0 is available for Unix-like operating systems.
