Command Line Overriding
If you specify embedded arguments, a final EXE will run as if the arguments are really passed to the program.
You can specify variables; for example, you pack notepad.exe, add a virtual file "1.txt" and specify "BoxedAppVar:ExeFullPath" 1.txt as an overrided command line. A packed notepad.exe will show 1.txt loaded from a virtual file.
