Download FileGriffon
FileGriffon is a file verification daemon for SSDs, HDDs and removable drives. It records cryptographic hashes of every file in a chosen folder, drive or single file, then rechecks those hashes on a schedule. Changes that occur without user action are reported. Files that are missing are separated from files that were moved or renamed, so folder reorganization does not appear as loss.
Damaged files can be restored using PAR2 parity data created in advance. The program includes a duplicate finder, monitors SMART drive health, and runs in the background with a tray icon and a local web dashboard. Its own database can be encrypted. All processing happens on the local machine, and no file contents, names or paths are transmitted.
A free tier covers one vault of any size without a time limit, including scheduled scans, corruption and move detection, database encryption, PAR2 repair at Light redundancy, and basic drive health monitoring. Pro adds unlimited vaults, whole-drive coverage, advanced SMART data, email and ntfy alerts, and the full PAR2 redundancy tiers. A 14-day trial is available inside the application. FileGriffon is written in Rust and has been in development since the early 2020s.
Use Cases for FileGriffon
| Vault represents folder, drive, share, or single file | Unlimited vaults on Pro, one vault on free tier |
| Cryptographic hash stored as file content fingerprint | Recomputed hashes compared against recorded values detect changes |
| Background daemon with tray icon and scheduled scans | Local web dashboard visualizes scan results and issues |
| Hash mismatch flags silent degradation without user action | Bit rot identified during scan rather than on file open |
| Analyzes vault to separate deleted from relocated files | Reorganized folders not misreported as data loss |
| PAR2 parity data reconstructs damaged file portions | Repaired originals set aside pending explicit confirmation |
| Duplicate Finder surfaces exact copies within monitored vaults | Reduces redundant storage consumption across collections |
| SMART data reads physical drive condition indicators | Degradation warnings precede complete disk failure events |
| Dashboard reports corruption, missing files, drive problems | Email and ntfy alerts available on Pro tier |
| Local database optionally encrypted to protect records | Does not encrypt user files, only program metadata store |
| Hashing and database remain entirely on user machine | No filenames or folder structures uploaded externally |
| License check sends one-way hashed machine fingerprint | Telemetry disabled by default, anonymized counts on opt-in |
| Free tier covers scheduled scanning and corruption detection | Pro adds unlimited vaults, advanced SMART, full PAR2 tiers |
