Quilty-Louise I don't know how many designs I have but I have two usb flash drives and I still have more room! Sewnsewer2, I try to view other sites but still go back to emblibrary. They also have good customer service. I can't download zip drives and they always come through for me to arrange the file so I may download it and for free! Love also that they keep a running category of all the designs one buys. Great backup!
