EPU is a disk compression util which allows you to virtually double the size of your harddrive - it's been around for some time but the nice chaps at NAUG have added an installer which makes the program far easier to use then ever before and easily puts it on level par with Power Computing's program. This program may NOT be sold by any other PD library unless express permission has been granted by the Northern Amiga Users Group, (they own the copyright to the installer!) So don't take it off the CD and advertise it. We'll be watching.
