NTFS is a file system primarily used by which operating system?

NTFS, which stands for New Technology File System, is primarily associated with the Windows operating system. It was developed by Microsoft and serves as the standard file system for Windows operating systems starting from Windows NT 3.1 and continuing through current versions, such as Windows 10 and 11. NTFS supports large files, file permissions for security, compression, and encryption, as well as advanced features like journaling which helps to ensure the integrity of the file system.

Other operating systems like Linux and macOS have their own native file systems, such as ext for Linux and HFS+ or APFS for macOS, although they may offer support for NTFS, primarily for compatibility purposes when accessing Windows partitions. Unix, which refers to a family of operating systems, has its own file systems as well, but NTFS is not natively used there. Thus, Windows is firmly established as the primary operating system that employs NTFS.
