New Technology File System - NTFS

By Tim Fisher, About.com

Definition: New Technology File System (NTFS) is a file system that was introduced by Microsoft in 1993 with Windows NT 3.1. NTFS supports hard drive sizes up to 256TB.

NTFS is the primary file system used in Microsoft's Windows NT, Windows 2000, Windows XP, Windows 2003 and Windows Vista operating systems.

The File Allocation Table (FAT) file system was the primary file system in Microsoft's older operating systems but it is still supported today along with NTFS.

Also Known As: NTFS
Examples: "I noticed a small increase in performance on one of my older hard drives once I converted it to the NTFS file system in Windows XP."
