NTFS (New Technology File System) is a file system used by the Windows NT operating system (and is also supported by Windows XP).

The NTFS file system uses a MFT (Master File Table) to locate all files within an NTFS volume. All critical data is duplicated to facilitate error recovery, ensuring the loss of one sector will not mean the loss of the entire partition. Additionally, it can recover data from a bad sector and ensure the bad sector is not used again.

NTFS also includes some advanced security features, including the ability to password protect individual files and/or folders.
