New Technology File System (NTFS) is a Windows NT based high performance and scalable 32 bitfile system. It supports files up to 10 terabytes and has a compression mechanism to reduce file sizes and minimize fragmentation.
The New Technology File System (NTFS) supports different cluster sizes to optimize disk space allocation for disks of different sizes. Security aspects are provided by logging the write operations in a journal. In addition, user rights for files and directories are defined in an access list. The NTFS file system is organized by the Master File Table( MFT), which contains the information about the stored files.
NTFS regenerates destroyed files and supports the use of the security database by Windows NT. If errors occur in the writing process, then these are eliminated by an error correction. For this the entry in the journal is deleted and the hard disk is transferred again into a write state. With the Encrypting File System( EFS) there is an NTFS extension for the encryption of files.
