Well, first off, that size selection is in MB, not GB, and you MIGHT wanna name it something different... (like, perhaps, oh, I don't know....cdrive?!?!?!)
And FTP'ing a >1GB file over a network...whoo, boy, you better have a good hour on your hands. (is it normal for it to be transferring at ~450KBps? With my calculations, it should be transferring at ~1125 KBps...)
