NestKeeper: Find exact duplicate files. Keep control of every cleanup.

Hey Product Hunt, I'm Deen from Krēˈādiv Worx. NestKeeper grew out of a familiar problem: years of downloads, backups and project folders full of copies of copies. It finds files with identical contents on your Windows PC, then lets you review which copies to keep. Scanning does not move or delete anything. Choose one folder, several folders or a deliberate broader scan; cleanup is a separate decision. Send selected extras to the Recycle Bin or move them to a same-drive review folder. You can reopen dated cleanup sessions, restore review-folder moves and export records. Advanced permanent deletion is available with extra confirmation; it cannot be undone. Keep independent backups and review your choices. NestKeeper 1.0.4 runs locally on 64-bit Windows 10 and 11, with no account, uploads, telemetry or subscription. The founding price is £9 GBP once plus applicable tax, including installer and portable versions for up to three personally controlled PCs. Current builds are unsigned and may trigger Windows SmartScreen. It finds exact duplicates, not visually similar photos. The screenshots use controlled sample files. There's a short captioned demo on our product page: https://blackstackdev.github.io/... What makes you hesitate before cleaning up duplicate files?
