NTFS (New Technology File System) is the standard file system of Windows NT, including its later versions Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, Windows Vista, and Windows 7.
NTFS supersedes the FAT file system as the preferred file system for Microsoft’s Windows operating systems. NTFS has several improvements over FAT and HPFS (High Performance File System) such as improved support for metadata and the use of advanced data structures to improve performance, reliability, and disk space utilization, plus additional extensions such as security access control lists (ACL) and file system journaling.
In the mid 1980s, Microsoft and IBM formed a joint project to create the next generation of graphical operating system. The result of the project was OS/2, but Microsoft and IBM disagreed on many important issues and eventually separated. OS/2 remained an IBM project. Microsoft started to work on Windows NT. The OS/2 file system HPFS contained several important new features. When Microsoft created their new operating system, they borrowed many of these concepts for NTFS. Probably as a result of this common ancestry, HPFS and NTFS share the same disk partition
NTFS has five released versions:
v1.0 with NT 3.1, released mid-1993
v1.1 with NT 3.5, released fall 1994
v1.2 with NT 3.51 (mid-1995) and NT 4 (mid-1996) (occasionally referred to as "NTFS 4.0", because OS version is 4.0)
v3.0 from Windows 2000 ("NTFS V5.0")
v3.1 from Windows XP (autumn 2001; "NTFS V5.1"), Windows Server 2003 (spring 2003; occasionally "NTFS V5.2"), Windows Vista (mid-2005) (occasionally "NTFS V6.0"), Windows Server 2008, Windows 7.
