NT File System (NTFS) (commonly called New Technology File System) is a proprietary journaling file system developed by Microsoft in the 1990s. [ 10 ] [ 11 ] [ 2 ] It was developed to overcome scalability, security and other limitations with FAT . [ 12 ]
Transactional NTFS (abbreviated TxF [1]) is a component introduced in Windows Vista and present in later versions of the Microsoft Windows operating system that brings the concept of atomic transactions to the NTFS file system, allowing Windows application developers to write file-output routines that are guaranteed to either succeed completely or to fail completely.

Under Windows 2000, NTFS 3.0 partitions can be set to keep track of changes to files and directories on the volume, providing a record of when and what was done to the various objects. When enabled, the system records all changes made to the volume in the USN Journal, which is the name also used to describe the feature itself.
System calls that create a file, but fail if the file already exists. (System calls are available from languages such as C or C++, and shell scripts can make use of noclobber) Using the mkdir command and checking the exit code for failure [11]
A typical new file creation event on an NTFS volume, then, simply involves NTFS allocating and creating one new MFT record, for storing the new file entity's file metadata—including, about any of the data clusters assigned to the file, and the file's data streams; one MFT record for a hard link which points to the first newly-created MFT ...
The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS [1] that provides filesystem-level encryption.The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
NTFS-3G supports partial NTFS journaling, so if an unexpected computer failure leaves the file system in an inconsistent state, the volume can be repaired. As of 2009, a volume having an unclean journal file is recovered and mounted by default. The ‘norecover’ mount option can be used to disable this behavior. [13]
Ntfsprogs was a collection of free Unix utilities for managing the NTFS file system used by the Windows NT operating system (since version 3.1) on a hard disk partition. 'ntfsprogs' was the first stable method of writing to NTFS partitions in Linux.
