FileGriffon checks your files for silent corruption.

A background service that runs on a schedule, verifies files with cryptographic hashing, and tells you the moment something's wrong — nothing else.

What FileGriffon is

FileGriffon is a background daemon that watches a drive or folder (a "vault") and cryptographically verifies your files over time. It flags corruption, missing files, and moved or renamed files, and can repair certain damage automatically using parity data. Everything runs locally — no cloud upload, no account required for the core features.

The idea: storage prices make "just buy a second drive and mirror it" a harder sell than it used to be. FileGriffon hardens the single drive you already have, at a fraction of the cost of buying redundant storage.

How it works

1

Point it at a folder or drive

Add any folder, drive, or NAS share as a "vault." No special formatting or preparation needed.

2

It scans on a schedule

Every file gets hashed and rechecked automatically in the background, on whatever cadence you set.

3

You get flagged, not surprised

Corruption, missing files, and moved or renamed files show up on the dashboard as soon as they're found — not whenever you next open the file.
