About UFFS - Ultra Fast File Search

UFFS reads the NTFS Master File Table directly, builds a compact persisted index,
and serves targeted queries in 0-3 ms daemon-side. One Rust engine for CLI, daemon,
TUI, and MCP agent workflows. Proven on 100M-record scale.

πŸ“¦ Downloads
UFFS is a Windows-native NTFS search engine β€” live indexing of
the Master File Table requires Windows. The engine core is
cross-platform, so macOS and Linux builds are shipped for
offline MFT analysis from captured .mft / .bin snapshots.
Each platform ships as a one-download ZIP bundle in three
tiers β€” pick the one that matches how much you need:
──────┬───────────┬─────────────────────────────────────────────────────────────────────
Tier β”‚Zip suffix β”‚Contents
──────┼───────────┼─────────────────────────────────────────────────────────────────────
min β”‚-min.zip β”‚uffs + uffsd + uffs-tui demo. Lean engine for CI/scripting.
──────┼───────────┼─────────────────────────────────────────────────────────────────────
normalβ”‚(no suffix)β”‚min + uffsmcp + uffs-mft + docs + brand + packaging helper.
β”‚ β”‚Recommended.
──────┼───────────┼─────────────────────────────────────────────────────────────────────
full β”‚-full.zip β”‚normal + the uffs-diag diagnostic tools.
──────┴───────────┴─────────────────────────────────────────────────────────────────────
> πŸ–₯️ Every tier bundles the free uffs-tui demo β€” the
> zero-setup front door. After unzipping, just run uffs-tui
> to browse your own drives in a UI (the daemon auto-starts).
> The demo has capped result counts and disabled exports; see
> DEMO-LICENSE.txt in the zip. Full TUI/GUI are commercial.
Individual binaries are also attached for automation that
wgets a single file.
