I like to shoot short films just for fun and I've been lugging around my wife's macbook air to copy footage from SD card to an external usb hard drive on location. Can I do this with a chrome book in offline mode? The drives are formatted ex-fat so they're windows and mac compatible, just not sure what file system chrome uses.

Thanks!
