Prove exact duplicates
SHA-256 narrows candidates, then a byte-for-byte check proves that two files really contain the same data.

Find wasted space.
Keep the right copy.

Why the download is not active yet: independent installer Round 2 closed every internal P1; its only remaining P1 is that the installer and main EXE still lack a trusted Authenticode signature. The 30-day launch clock has not started.

From folders to a recoverable cleanup plan in 42 seconds.
The tour uses real 0.9.0 application captures. It shows the boundary between exact proof and review-only similarity, then explains that signing and the independent installer gate must both pass before public download.

Broad enough for real collections
Exact files, photos, audio, video, folders, and archives.
Every mode states whether it proves identical content or only suggests a match for human review.
Review similar media safely
Find resized or rotated photos, matching audio, and related video frames without treating approximate matches as safe to auto-delete.
Keep the right copy
Protect reference folders, keep the newest, oldest, shortest path, or a name-pattern match, and see the reason beside every decision.
Undo cleanup
Use the Recycle Bin or a verified quarantine ledger. Restore returns the file to its original path and verifies its contents.
Replace copies with hard links
Keep both paths while reclaiming physical storage. A durable recovery ledger can reconstruct independent copies later.
Repeat professional scans
Save profiles and sessions, reuse a persistent hash cache, export CSV/JSON/HTML, or automate scans through the CLI.
Deletion is the last step
A duplicate finder should earn permission to clean.
UtiliVera separates discovery, selection, planning, and mutation. Similar photos, audio, video, names, and folders remain review-only. Only byte-verified exact groups can enter automatic cleanup.
- Reference locations cannot be selected for cleanup.
- The final copy in every group remains protected.
- Existing hard links do not inflate reclaimable-byte totals.
- Settings, cache, quarantine, and recovery ledgers are self-excluded.
- 1ScanChoose locations and the exact or review-only mode.

What to know before the release.
The product audit passed. Public release remains intentionally held until signing and the separate installer review both pass.
Is UtiliVera Duplicates free?+
Yes. Version 0.9.0 is freeware for personal, educational, nonprofit, and commercial work.
Does it upload file names or contents?+
No. Scanning, hashing, previews, cleanup planning, and restoration run on the Windows PC.
Does the app delete similar photos automatically?+
No. Approximate image, audio, video, file-name, and folder matches are review-only. Automatic selection is limited to exact byte-verified groups.
Can cleanup be undone?+
Recycle Bin and quarantine workflows are recoverable. Hard-link replacement creates a durable ledger that can reconstruct independent verified copies.
What does the installer require?+
Windows 10 or 11 x64 with Microsoft .NET Framework 4.8. The installer checks this prerequisite before copying files.
Why can I not download it yet?+
Independent installer Round 2 closed every internal P1. Its only remaining P1 is that the 3.77 MiB installer and main EXE are not Authenticode-signed.
