new pc old sync folder

[butterflies]

Hello,
I have upgraded my pc and have the old folder with ipad photos back upped. How do I set up iTunes so that it doesn't delete or even replace the existing photo library and neither any app from the iPad? How do I get the existing iPad apps in the iTunes library?
Thanks,
Rob

I moved it there.
