Editor to share with you what the ntfs format means, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

The full name of ntfs is New Technology File System, which means "new technology file system" in Chinese. It is a disk format specially designed for network and disk quota, file encryption and other management security features.

NTFS (New Technology File System) is a disk format specially designed for network and disk quotas, file encryption and other management security features supported by a series of operating systems of the Windows NT kernel. It provides long file names, data protection and recovery, security through directory and file licenses, and support for cross-partition.

NTFS is a journaling file system, which means that in addition to writing information to disk, the file system keeps a log of all changes that occur. This feature makes the NTFS file system easier to recover in the event of an error, such as a system crash or power outage, and makes the system stronger. In these cases, NTFS can quickly return to normal without losing any data. With few errors, Microsoft says there is a particularly low probability that you need to run CHKDSK fixes to maintain disk volumes, which is less than 1%.

Features of the NTFS file system

NTFS file system has three functions: error warning function, disk self-healing 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 change 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. On the other hand, the FAT of FAT16 and FAT32 can only be fixed behind the partition boot sector, and once the sector is damaged, the entire file system will be paralyzed.

Disk self-repair function: NTFS can automatically detect and repair logical and physical errors on the hard disk. It checks whether the sector is correct each time it reads or writes. When an error is found while reading, NTFS reports the error; when an error is found while writing a file to disk, NTFS stores the data in an intact location.

Logging function: in the NTFS file system, any operation can be regarded as an "event". The event log monitors the entire operation all the time, and when it finds the complete file at the destination, it marks "completed". If the power is cut off in the middle of the replication, "completed" will not be recorded in the event log, and NTFS can recomplete the previous event after an incoming call.
