The EXE packer, UPX

This tool is mainly useful for programmers who want their releases packed to the bone.

Everyone can still use it for shrinking any executable (.exe file), though.

UPX v3.0.3



How to use:

1. Download the package from the official website or just the zipped program as provided in this link.
2. Extract the contents of upx.zip and move upx.exe to C:\Windows or any of your folders included in the PATH system variable.
3. Run a cmd shell and change path to the target EXE file.
4. Type in "upx -9 <Exe FileName>" for maximum compression.

Note: Just run upx for a list of available command parameters.

That's it.
