NT File System (NTFS) (commonly called New Technology File System) is a proprietary journaling file system developed by Microsoft in the 1990s as the successor to the File Allocation Table (FAT) file system.
It was developed to overcome the scalability, security, and other limitations of FAT. NTFS adds several features that FAT and HPFS lack, including access control lists (ACLs), filesystem encryption, transparent compression, sparse files, file system journaling, and volume shadow copy.
Starting with Windows NT 3.1, it is the default file system of the Windows NT family, superseding the File Allocation Table (FAT) file system.
NTFS uses several files hidden from the user to store metadata about other files stored on the drive, which can help improve speed and performance when reading data.
NTFS was slated to be replaced by WinFS, one of the anchor features of the Longhorn platform. However, WinFS was cancelled after Microsoft was unable to resolve performance problems with the file system.
