This VB Add-In is a GUI for the wonderful UPX compression utility (The Ultimate Packer for eXecutables, written by Markus Oberhumer & Laszlo Molnar at upx.sourceforge.net). It allows you to compile and compress your project with a single click of button on the VB 6.0 toolbar. Compression allows you to add some protection to your project + faster loading times on the network and etc.

Please read the UPX documentation carefuly.
