Copying and transfering files between a Mac and a Windows PC can be frustrating. Especially when your file size exceeds 4GB, which means USB-Sticks and hard drives formattetd in MS-DOS FAT32 won’t work. But there’s a solution called ExFat (Wikipedia link). Your Mac can read and write on ExFat formatted drives (starting with Snow Leopard) and so can a Windows machine. The single file size is as good as unlimited. Just pop your drive or stick in to your Mac and open Disk Utility to format it in ExFat. You now have the perfect solution for swapping data between the two worlds – OS X and Windows.
