Core NTFS structure: MFT (Master File Table) with 1 entry per file, recording attributes, ACLs, dates and pointers to data clusters. Journaling in $LogFile enables fast post-crash recovery. Integrated Volume Shadow Copy (VSS) allows point-in-time snapshots. Supports volumes up to 256 TB (with default 4KB cluster size) or up to 8 PB (64KB cluster). NTFS is the most common Windows data recovery scenario. In corruption, professional tools rebuild MFT from backup copies ($MFTMirr) and fragments. In quick format, the old MFT is often recoverable until new data overwrites specific clusters.
