It 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 for most of the formats supported. It allows a compression of all the .exe and .dll.

The compression factor is impressive. We haven't found any problem with our applications running on WNT and W2K. The size of an .exe of 5623 Kb. drops down to 784 Kb. (1-7 ratio) !

This product is a shareware and you can download it from http://upx.sourceforge.net

You can also set VOPP to run it automatically when an application is being rebuild.

This is the source code of the upx.tpl I use with VOPP : upx %fullfile% ( it shouldn't be too difficult to install <g>)
