NTFS (New Technology File System) is a disk format supported by the Windows NT kernel series operating systems. It is specially designed for management security features such as network and disk quotas, file encryption, etc. It provides long file names and data protection. and recovery, with security through directory and file permissions and support for spanning partitions.

NTFS is a journaling file system, which means that in addition to writing information to the disk, the file system also maintains a log of all changes that occur. This feature makes the NTFS file system easier to recover when an error occurs (such as a system crash or power supply interruption) and makes the system more robust. In these cases, NTFS can recover quickly without any data loss. In the unlikely event that something goes wrong, Microsoft says the chance that you'll need to run the CHKDSK repair program to perform maintenance on the disk volume is extremely low, at less than 1%.

Function of NTFS file system

NTFS file system has 3 functions: error warning function, disk self-repair function and Logging function.

Error warning function: In the NTFS partition, if the disk sector where the MFT is located happens to be damaged, the NTFS file system will intelligently replace the MFT to other sectors of the hard disk, ensuring the normal use of the file system , that is, ensuring the normal operation of the system. The FAT of FAT16 and FAT32 can only be fixed behind the partition boot sector. Once the sector is damaged, the entire file system will be paralyzed.

Disk self-healing function: NTFS can automatically detect and repair logical errors and physical errors on the hard disk. During each read or write, it checks whether the sectors are correct or not. When an error is found when reading, NTFS will report the error; when an error is found when writing a file to the disk, NTFS will store the data in a good location.

Log function: In the NTFS file system, any operation can be regarded as an "event". The event log monitors the entire operation and marks "completed" when it finds a complete file at the destination. If the power is lost during the copy, "Completed" will not be recorded in the event log, and NTFS can re-complete the event after the call comes back.
