NTFS – New Technology File System
Definition: New Technology File System (NTFS) is a file system that was introduced by Microsoft in 1993 with Window NT 3.1. NTFS supports hard drive sizes up to 256TB.
NTFS is the primary file system used in Microsoft’s Windows 7, Windows Vista, Windows XP, Windows 2000 and Windows NT operating systems. The Windows Server lines of operating systems also primarily use NTFS.
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.
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.
