GUiPeX v1.4.0.5

UPX front-end

GUiPeX is a name taken from GUI (Graphical User) and UPX. 

UPX, a free DOS command-line , is a portable, extendable, high-performance executable packer for several different executable formats. It achieves an excellent compression ratio and offers very fast decompression. Your executables suffer no memory overhead or other drawbacks. Since UPX is a DOS , a simple GUI front-end for use in Windows was needed.
