KGB Archiver
KGB Archiver is a discontinued file archiver and data compression utility that employs the PAQ6 compression algorithm.[2] 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.[3] As a consequence, the program uses memory and CPU intensively.
