Transfering psp files

im trying to transfer a saved file in my computer to my psp but i forgot how.
im not sure what im looking for to do the whole transferring.

Just connect your psp into your pc then:
--+PSP

--+SAVEDATA

--+YOURGAMEFOLDER(Put your PSP save file in there)

Done...

depending on what you are transfering.If its just a regular file and you are doubling your psp as a thumb drive,its fine if you paste it outside the folders.

If its psp games,you have to paste it in the game/ISO folder I think,havnt booted up my psp in a while.
