Īlthough subsequent versions of Windows added new file system-related features, they did not change NTFS itself.

NTFS 1.0 is incompatible with 1.1 and newer: volumes written by Windows NT 3.5x cannot be read by Windows NT 3.1 until an update (available on the NT 3.5x installation media) is installed. Microsoft has released five versions of NTFS: Algorithms identifying the file system in a partition type 07 must perform additional checks to distinguish between HPFS and NTFS. For example, FAT has more than nine (one each for FAT12, FAT16, FAT32, etc.).

Using the same Partition ID Record Number is highly unusual, since there were dozens of unused code numbers available, and other major file systems have their own codes. Probably as a result of this common ancestry, HPFS and NTFS use the same disk partition identification type code (07). The original NTFS developers were Tom Miller, Gary Kimura, Brian Andrew, and David Goebel. When Microsoft created their new operating system, they "borrowed" many of these concepts for NTFS.

The HPFS file system for OS/2 contained several important new features. Because Microsoft disagreed with IBM on many important issues, they eventually separated OS/2 remained an IBM project and Microsoft worked to develop Windows NT and NTFS. In the mid-1980s, Microsoft and IBM formed a joint project to create the next generation of graphical operating system the result was OS/2 and HPFS.

7.4 Attribute lists, attributes, and streams.

NTFS also supports shadow copy to allow backups of a system while it is running, but the functionality of the shadow copies varies between different versions of Windows. Unlike FAT and High Performance File System (HPFS), NTFS supports access control lists (ACLs), filesystem encryption, transparent compression, sparse files and file system journaling. NTFS uses several files typically hidden from the user to store metadata about other files stored on the drive which can help improve speed and performance when reading data. Windows can convert FAT32/16/12 into NTFS without the need to rewrite all files.

NTFS reading and writing support is provided using a free and open-source kernel implementation known as NTFS3 in Linux and the NTFS-3G driver in BSD. It superseded File Allocation Table (FAT) as the preferred filesystem on Windows and is supported in Linux and BSD as well.

Starting with Windows NT 3.1, it is the default file system of the Windows NT family. New Technology File System (NTFS) is a proprietary journaling file system developed by Microsoft.
