How large is the full Maplestory (Nexon) file?

Currently, all Nexon websites are being updated, so they are non-accessible. I need to know the exact or educated approximation of the ammount of memory Maplestory takes up?? I need to download it onto a 2GB flashdrive, and I'm hoping 2GB will be enough! Also, if it is more than 2GB, is there a way to download part of it on my laptop, part of it on my flashdrive, and still have it work? I can't download the file to my actual laptop because of risk of viruses, and lately I've been DYING to play maplestory. Incase it's important, I have a Toshiba laptop, The latest version of Windows, and microsoft. I really need a thorough answer from somebody who knows what they're talking about. Thanks:).
