(A very small software application that offers a front-end for the Upx program
Well, Upx Gui is exactly what its name says, a front-end for the Upx application.
Upx Gui features context menu integration, compression settings and an auto shutdown option.
The program now also scans the selected file with the help of PEid. After this scan, it determines the thing to do, compress, or de-compress.)
