 Although Windows does not natively support HFS+, an HFS+ volume on an AirPort Disk can be easily accessed from Windows.This is because the SMB/CIFS protocol used to access the disk, and hence access from Windows is filesystem-independent.Therefore, HFS+ is a viable option for Windows as well as OS X users, and more flexible than FAT32 as the latter has a 4 GiB file size limit.
