Practical guide
Find byte-for-byte duplicate files without uploading a folder
Audit a selected folder for identical files by comparing sizes and local SHA-256 hashes. The report is read-only: the tool does not delete, move, or rename files, so every cleanup decision remains under your control.
Common uses
- Find repeated exports or downloads before archiving a folder.
- Review duplicate photos or documents while preserving their paths.
- Generate a text report for a manual cleanup pass.
What to expect
- Comparison
- Files with matching sizes are hashed, and only matching SHA-256 values are grouped as duplicates.
- Scope
- Select up to 500 files with a combined size of 2 GB.
- Safety
- The tool is intentionally read-only and cannot remove files from the device.
