It is a super compressor and integrates the command line compressor UHARC v0.6b, created by Uwe Herklotz, into the Windows shell. UHARC CMD is unique from other. UHARC GUI's in that it doesn't use any compiled source code to interface UHARC with the Windows Shell. It uses a set of batch scripts. The installer and UHARC CMD settings are compiled using NSIS. It's as easy as right clicking on files/folders and clicking compress!
