RobertasTa.SmartDuplicateFinder 1.3

Safe, portable duplicate file finder that never deletes your files.

Finds duplicate files by content (MD5) and visually similar photos (perceptual hash), including the iPhone HEIC and AVIF formats that Windows itself often cannot open. Two-phase scan with a guided candidate dialog and per-family time estimates. Results are colour-grouped by file family with a colour-coded Excel report, so you can clean up at your own pace. Right-click a result to open the file, open its folder or copy its path - opening is deliberately disabled for executable files. By design the program never deletes your files - the only optional deletion is invisible system junk (Thumbs.db, .DS_Store) verified by content signature before removal. One exe for all UI languages (English, Lithuanian, Russian and German, switchable in-app, first run follows the Windows language). Optional portable mode keeps all working files next to the exe and leaves no traces on the computer. Portable single exe: no installation, no ads, no telemetry, no network access.
