How do I use a UMD rip?

I have a UMD rip of a game. I have a PSP. I have a memory stick in it large enough to fit the game.

Now, tell me, HOW THE FUCK DO I PLAY THIS THING ON MY PSP? I've tried loading the PSP_GAME folder and UMD DATA file into the GAME folder in my PSP, but when I try to play it, it just comes up as a corrupted file. Do I have to make a different folder for it, or do something else with it, or what?
