**A from-scratch, forensic-grade NTFS reader — `$MFT`, attributes, indexes, data runs, named streams, LZNT1, and `$UsnJrnl:$J` change-journal records over any `Read + Seek` source. No `unsafe`, no C bindings.**

```toml
[dependencies]
ntfs-core = "0.6"
```

```rust
use ntfs_core::NtfsFs;
use std::fs::File;

let mut fs = NtfsFs::open(File::open("ntfs.img")?)?;

// Read a file by path…
let hosts = fs.read_file(r"\Windows\System32\drivers\etc\hosts")?;

// …or list the root directory (MFT record 5).
let root = fs.read_record(5)?;
for entry in fs.directory_entries(&root)? {
    if let Some(name) = entry.file_name {
        println!("{}", name.name);
    }
}
# Ok::<(), ntfs_core::NtfsError>(())
```

The bare crate name `ntfs` on crates.io is Colin Finck's general-purpose reader, so this crate publishes as **`ntfs-core`** and imports as **`ntfs_core`**.

## What it parses

`BootSector` (BPB / extended BPB) · `MftRecordHeader` + `apply_fixup` (FILE records, update-sequence-array fixup) · `parse_attributes` (resident + non-resident) · `StandardInformation` / `FileName` (both timestamp sets) · `decode_runlist` + `read_attribute_value` (data runs, sparse, non-resident) · `IndexRoot` / `parse_index_buffer` (directory `$INDEX_ROOT` / INDX) · `parse_attribute_list` (fragmented files) · `decompress` (LZNT1) · `carve_mft_entries` (`FILE`/`BAAD` carving) · `compare_mft_mirror` / `parse_logfile` (`$MFTMirr`, `$LogFile`). Open a partition inside a whole disk with the bounded `OffsetReader`, which structurally cannot read past the volume boundary.

### `$UsnJrnl:$J` change journal

A full change-journal reader, not just a record decoder:

- `parse_usn_record_v2` / `parse_usn_record_v3` / `parse_usn_journal` · `UsnRecord` / `UsnReason` / `FileAttributes` — decode V2/V3 records (MFT + parent-MFT references, reason flags, filename, attributes, timestamp).
- `UsnJournalReader` — streaming, low-memory iterator over a `$J` stream too large to load whole.
- `carve_usn_records` — recover USN records from free space and corrupt journals (V2/V3, timestamp-range gated).
- `RewindEngine` — CyberCX two-phase (reverse + forward) **full-path reconstruction** with rename / MFT-reuse handling.
- `MftData` / `MftEntry` — high-level `$MFT` aggregator (`$SI`/`$FN` timestamps, ADS, path resolution) that seeds the `RewindEngine`.
- `RefsAnalyzer` / `RefsFileId` — ReFS USN V3 support (128-bit file IDs, journal-rewind-only path reconstruction).

## Trust, but verify

`#![forbid(unsafe_code)]`; panic-free on crafted input (the workspace denies `clippy::unwrap_used` / `expect_used` in production code, every length and offset bounds-checked); fuzzed with seven `cargo-fuzz` targets; the boot parser is cross-validated against The Sleuth Kit on a real disk image and MFT parsing against the `mft` crate as an independent oracle; 100% line coverage enforced in CI.

## Forensic analysis

Severity-graded anomaly auditing (timestomp / ADS / deleted-record / slack / `$MFTMirr` / `$LogFile` findings) lives in the sibling **[`ntfs-forensic`](https://crates.io/crates/ntfs-forensic)** crate, built on this one — the reader/analyzer split mirrors `vmdk-core`/`vmdk-forensic`.
