NTFS is the primary file system of all modern versions of Windows.

NTFS is the primary file system of all modern versions of Windows and is largely backward-and-forward-compatible in all supported versions. It is a journaling file system which makes it robust in the face of system failure, and in Vista/Windows Server 2008 and later offers support for transactions. It supports transparent compression and encryption and full access-control-list-based security.
