Questions tagged [ntfs-mft]

Master File Table (MFT) is an integral component of the NTFS file system. The MFT contains metadata about every file, directory, and metafile on an NTFS volume. It includes filenames, locations, size, and permissions.

The Master File Table (MFT) contains metadata about every file, directory, and metafile on an volume. It includes filenames, locations, size, and permissions. Its structure supports algorithms which minimize disk fragmentation. A directory entry consists of a filename and a "file ID", which is the record number representing the file in the Master File Table. The file ID also contains a reuse count to detect stale references.
