What is an nstf partition?

NTFS is the standard file system of Windows NT and higher versions of Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, Windows Vista and Windows 7. NTFS replaced the file allocation table (FAT) file system and provided a file system for Microsoft's Windows operating system. NTFS has made some improvements to FAT and HPFS (High Performance File System), such as supporting metadata, using advanced data structures to improve performance, reliability and disk space utilization, and providing some additional extended functions, such as access control list (ACL) and file system log. The detailed definition of this file system is a trade secret, but Microsoft has registered it as an intellectual property product.

Characteristics of NTFS

Supported size

NTFS can support partitions up to 2TB (called volumes if dynamic disks are used). FAT32 in Win 2000 supports partitions with a maximum size of 32GB.

Reliable file system

NTFS is a recoverable file system. Users rarely need to run disk repair programs on NTFS partitions. NTFS ensures the consistency of partitions by using standard transaction logs and recovery techniques. When the system fails, NTFS uses log files and checkpoint information to automatically restore the consistency of the file system.

Support folder compression

NTFS supports the compression of partitions, folders and files. When any Windows-based application reads and writes compressed files on NTFS partition, it is unnecessary to decompress them with other programs first. When reading a file, the file will be automatically decompressed. Files are automatically compressed when they are closed or saved.

Effectively manage disk space

NTFS uses smaller clusters to manage disk space more effectively. Take the FAT32 file system of Win 2000 as an example. When the partition size is 2 GB ~ 8 GB, the cluster size is 4 KB. When the partition size is 8 GB ~ 16 GB, the cluster size is 8 kb; When the partition size is 16GB ~ 32GB, the cluster size reaches 16KB. In the NTFS file system of Win 2000, when the partition size is less than 2GB, the cluster size is smaller than the corresponding FAT32 cluster. When the partition size is above 2GB (2 GB ~ 2 TB), the cluster size is 4KB. In contrast, NTFS can manage disk space more effectively than FAT32 and avoid the waste of disk space to the maximum extent.

Better security

On NTFS partitions, you can set access permissions for * * * resources, folders and files. Permission setting includes two aspects: first, which groups or users are allowed to access folders, files and * * * resources; The second is what level of access groups or users can have. The setting of access rights not only applies to users of local computers, but also applies to network users who access files through * * * shared folders on the network. Compared with accessing folders or files under FAT32 file system, the security is much higher. In addition, in Win 2000 with NTFS format, folders, files and active directory objects can be audited by applying audit policies, and the audit results are recorded in the security log. Through the security log, we can see which groups or users have operated on folders, files or active directory objects at what level, so as to find out the illegal access that the system may face and take corresponding measures to minimize this security risk. These are not possible under the FAT32 file system.

More function

Disk quota management can be carried out under the NTFS file system of Win 2000. Disk quota means that the administrator can limit the disk space that users can use, and each user can only use disk space within the maximum quota. After setting the disk quota, you can track and control the disk usage of each user, and identify users who exceed the quota warning threshold and quota limit through monitoring, so as to take corresponding measures. By providing disk quota management function, administrators can allocate storage resources for users conveniently and reasonably, avoid the possible system crash caused by out-of-control use of disk space, and improve the security of the system. NTFS uses the Change log to track changes that have occurred in the log file. There are many things related to system services, such as encrypting file data.
