Coping iTunes library from a laptop XP to a laptop using Windows 8. I have loaded iTunes on the new computer. I have exported the library to a flash drive. I cannot find how to import the library.

I have tried three different ways suggested on the net to copy my library from my older computer which uses XP to my new laptop which uses Windows 8. I have dowloaded iTunes to the new computer. I have aslo exported the library to a flash drive (I think). When I go into the iTunes on the new computer, I cannot find whwere to import from the flash drive. P.S. I also have an iPod with the library on it. Would appreciate help.
