Lol, you don't know?
Newton's first law states that an object in motion wants to stay in motion.
So, throw your first PC at your second one. The first PC will stop moving upon contact, but the files in it will continue moving, according to Newton's first law. The files will then travel out of the first PC and into the second PC.
But be careful, if you don't throw it hard enough, the files will not penetrate through the PC, and will remain stuck inside forever. And even worse, if you throw it JUST A BIT less than you should, the files will penetrate out of the first PC, but will NOT be able to enter the second one, since the files will lose some energy going out of the first PC. In this case, the files will be lost, and you'll never be able to play the game anymore.
And of course, in that case you'll give me your key (since you can't use it anymore) and I'll sell it since I already have one.
It's okay, you'll learn it soon enough if you stay in school!
