hi sorry the title is a bit confusing. iv bought my sister a 128gb USB stick for xmas and I'm putting some stuff on there for her.
my question is - i am using a macbook, but she will be using the usb on a windows laptop. do i format it before i put anything on, or just drag the stuff over and not bother formatting because it isn't gonna be used on my mac? i know even now it may be a bit vague what I'm after but hopefully someone knows what I'm on about!
