Detail the internal architecture, file records, and storage mechanisms of the Windows New Technology File System through the structure of the Master File Table.
Architectural analysis of NTFS file records, Master File Table structures, and multiple data stream attributes using diagrammatic models.
Technical review of core file system features, including hard links, 8.3 legacy names, reparse points, transaction journals, sparse files, and compression mechanisms from a developer perspective.
Demonstrates how file records within the Master File Table store file metadata and handle secondary streams such as Zone.Identifier attributes.
Explains the implementation and interaction of reparse points, dual-journal logging systems, and space-saving routines for sparse and compressed files.

Implication

Technical review details NTFS structural components and master file table operations for Windows developers, highlighting internal mechanisms like reparse points and journaling.

Abstract

Part 5 of a series explaining NTFS internals with diagrams. Covers the MFT and file records, multiple data streams (Zone.Identifier), hard links and 8.3 names, reparse points, the two journals, and sparse files and compression — all organised from a developer's point of view.
