Introduction of NTFS

NTFS (New Technology File System) is a standard file system for Windows NT and then developed in Windows versions like Vista, XP. It replaces the file allocation table (FAT) file system and provides a file system for Microsoft's Windows family of operating systems. And NTFS made several improvements to FAT and HPFS (High Performance File System), for example, to support metadata, and used advanced data structures to improve performance, reliability, and disk space utilization. Besides, it provided several additional extensions such as access control lists (ACLs) and file system logs. And NTFS has no limiting size of single files and it owns the top capacity of 256TB for partition size.
