Gamesave Help

I downloaded a LBP gamesave. It came out as a zip file. I tried to put that onto my PS3 via memory stick but it didn't work, I then tried unzipping the file and putting the folder on the memory stick and then into my PS3 but that still didn't work. I then tried putting the folder components, the actual files, onto the memory stick and into my PS3 but that didn't work either. Is there anything else you can suggest?

it may not work... sony has really blocked that kind of stuff.

and you cant get trophies that way.
