No program needed, although they are available on www.download.com
Just plug in your PSP with the USB cord, and go to USB mode on the far left in your PSP, if it doesnt automatically do it. Then your computer should pop up as recognizing the PSP in the bottom right. If not, go to My Computer and you should see your PSP in there. From there drag and drop the items you want to the PSP memory stick duo that you have in it. If you dont have a memory stick, you will have to get one.
