MAINTAIN
Survey. Compare. Clear what no longer belongs.
Three local-first tools for keeping a machine understandable over time: compare directory states, review duplicate files safely, and see where disk space actually went.
These tools treat the filesystem like terrain: compare layers, identify redundancy, and measure where space is accumulating before changing anything.
Rift
See exactly what changed.
Compare two folder trees without modifying either one. Rift classifies files as added, removed, changed, or unchanged and uses SHA-256 when content needs verification.
- Read-only directory comparison
- SHA-256 content checks
- Likely rename detection
- JSON and CSV export
Cull
Find duplicates. Decide safely.
Cull groups exact duplicates by content, surfaces near-name candidates for review, calculates reclaimable space, and uses reversible quarantine instead of permanent deletion.
- Exact duplicate grouping
- Near-name review candidates
- Reclaimable-space estimates
- Reversible quarantine workflow
Quarry
Find what is consuming the drive.
Quarry scans a directory and turns storage into a readable survey: biggest files, top-level usage, extension totals, age buckets, and a visual treemap of what is taking up space.
- Largest-file analysis
- Folder, extension and age totals
- Treemap-style visualization
- JSON export
