UPX is a program that allows you to immediately package executable files, after which they will take up a minimum of space on your computer's hard drive, and at startup will be unpacked directly into the computer's memory.

The UPX program supports a large number of file formats, including COM, EXE and SYS.

Great software for saving space on your laptop. My computer is a bit old, and running out of space. After using UPX, my laptop runs a lot faster now. Would recommend this to anyone with slightly older laptops or looking to save space.
