Don't woried try this software, i think is one of the best software evermade, even vista don't have this function integrated, install it,
just block the file u want to copy, and drag it with right click to destination folder, release it, then it will show few context menu, choose one u like to do, and the windows will open with pause and resuming button
i know it already man but i don't know it slower than the normal windows copy so i don't use it any more it was faster on win98 but on xp the nowmal xp copy is alot faster
