What Is NTFS (New Technology File System)?

New Technology File System or NT file system (NTFS) provides virtual space to organize and store files. It also notes file positions in folders, creation dates, and details about access, and provides data encryption. 

NTFS was developed by Microsoft and launched in 1993 to replace its predecessor, the file allocation table (FAT) system, for better performance and enhanced data support. Recent Windows versions and various operating systems in Windows Server use NTFS as the primary system. Learn more about the key features of NTFS. 

Key features of NTFS

The NTFS system offers advanced functions, including increased reliability, security encryptions, large volume support, and administrative control, making it a high-performance and powerful storage solution.

• Journaling file system: One of the essential features allowing NTFS to improve the reliability of the system and data integrity is its transaction journal. A particular benefit is that it completes its journaling before making changes to the disk, which allows faster recovery without data loss in the instance of a power or system failure in the midst of disk changes.

• Advanced security: The Access Control List (ACL) feature grants administrators authority to set permissions for specific groups or users to access or restrict files and folders. BitLocker Drive Encryption provides device encryption support, which increases the security level for critical system information and stored data. The encryption prevents access from external sources by blocking files needed to discover the user’s passwords.

• Extensive volume support: On newer versions of Windows, including Windows Server 19, Windows 10 version 1709, and newer, NTFS supports volumes as great as eight petabytes, although the size and number of clusters can impact the system’s capability.

NTFS for Mac

You can use a program called NTFS for Mac to interact with NTFS files on a Mac computer. 

• Logging: Tracking files is conveniently done by an administrator through the master file table’s logging and auditing system. Records provide access to see what has been added, removed, or altered.

• Capacity allocation: Administrators have the capacity to assign disk usage quotas to individual users, which is effective for tracking and controlling space used on shared network drives.

• Quick access to files: NTFS uses complex binary trees to index files, enabling rapid retrieval for file access.
