Knowra NTFS NTFS NTFS is a journaling file system developed by Microsoft for Windows. It organizes files and directories in a master file table and supports permissions, compression, and large volumes.
Master File Table : The NTFS database that stores records describing files, directories, and their metadata. Each file is represented by an MFT record, which can also hold small files’ contents.
File metadata : Information describing a file, such as its name, size, timestamps, and permissions. NTFS stores file metadata in records that let Windows identify and manage files.
NTFS permissions : Windows access rules attached to NTFS files and directories. These permissions determine which users can read, modify, or execute stored objects.
FAT32 : A widely compatible file system with limits on individual file size and volume capacity. FAT32 works across many devices but lacks several protections and capabilities offered by NTFS.
Windows NT : Microsoft’s operating-system family first released in 1993, built around a protected, portable architecture. NTFS was created for the Windows NT family and became its principal file system.
NTFS journal : A log of filesystem metadata changes used to restore consistency after an interruption. NTFS records metadata operations in its journal before applying them to disk.
Access control list : A list specifying which users or groups may perform particular actions on an object. NTFS security descriptors use access control lists to govern file and directory access.
NTFS compression : A feature that compresses files or directories on an NTFS volume. Compression reduces storage use while letting Windows access files through NTFS.
exFAT : A Microsoft file system designed for flash storage and large files across devices. exFAT favors removable-media compatibility, while NTFS offers richer Windows filesystem features.
OS/2 : An operating system initially developed jointly by IBM and Microsoft. NTFS development drew on ideas from the HPFS filesystem associated with OS/2.
