Hey Product Hunt community! 👋 I'm Zhenqiang, creator of DirMerge. Like many of you, I've lost count of how many times macOS Finder gave me cold sweats whenever I needed to consolidate two similar folders. Whether it was reorganizing Lightroom photo archives across external SSDs, cleaning up duplicate client deliverables, or merging two divergent project branches without git, Finder's clumsy "Replace or Keep Both" prompt always felt like a trap waiting to erase my files. When Apple introduced APFS with Copy-on-Write (CoW) extents years ago, I realized something: why are we still duplicating gigabytes of raw data blocks on expensive Mac SSDs when the operating system can clone files in milliseconds for ZERO extra bytes of storage? So I built DirMerge with three non-negotiable principles: 1. Zero-Space Speed: On APFS drives, it merges files instantaneously using Darwin's native copyfile cloning. 2. Complete Peace of Mind: The Source folder is strictly read-only, and any overwritten file in the Target folder is backed up into an instant ⌘Z rollback snapshot. You can never lose files. 3. Radical Privacy: DirMerge is 100% offline. The binary doesn't even contain the network entitlement (com.apple.security.network.client). No telemetry, no accounts, no cloud sync. Pricing is straightforward: - Free Tier: Full APFS zero-space cloning for up to 25 items per batch merge. - Pro Lifetime ($9.99 USD): Single one-time purchase unlocks unlimited batch processing on all your Macs forever. No subscriptions. I would love to hear your feedback, feature requests, or wild folder synchronization edge cases. I'll be hanging out here all day to chat! What's the worst folder merge disaster you've ever had on a Mac? 😅
