NT File System (NTFS) is a proprietary journaling file system developed by Microsoft in the 1990s.

It was developed to overcome scalability, security and other limitations with 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, a feature that allows backups of a system while in use.
