KoiFiles (双鱼文件): The all-in-one dual-pane file workspace for macOS

Hey Product Hunt community! 👋 I’m [Your Name], the creator of KoiFiles. Like many of you, I spend hours managing assets, code repos, and archives on my Mac every single day. While Finder is clean, it constantly forced me into a messy multi-app setup: Multiple overlapping Finder windows just to organize directories. A separate tool just to preview inside 7z/RAR archives without full decompression. Another heavy disk cleaner running background daemons. I wanted a modern, blazing-fast file workbench that brings the efficiency of dual-pane workflows without the bloat of legacy 20-year-old file managers. So I built KoiFiles. What makes KoiFiles different? ⚡️ Native & Modern: Built exclusively with SwiftUI for Apple Silicon (macOS 14+). Zero Intel legacy bloatware. 🗂 Dual-Pane + Tabbed Workflow: Drag and drop side-by-side or stacked, with full keyboard-first cut/copy/paste parity. 📦 Embedded 7zz Engine: Native encryption, compression, and lightning-fast archive inspection (7z, ZIP, TAR, etc.). 👁 Non-blocking Gallery Preview: Instant Spacebar inspection that doesn't freeze your active file operations. 🧹 Standalone Disk Cleaner: Safely reclaim storage (large files, duplicates, cache) in a detached task window while you work. 🔒 Zero Telemetry & Non-SaaS: We don't upload your files, track your clicks, or charge you an endless monthly subscription. Distribution & Transparency: We offer a fully functional DMG build directly from our site for unrestricted direct file access, while the Mac App Store license acts as your lifetime key. Special PH Launch Offer 🎁 As a thank you to the PH community, we’re offering [e.g., 30% OFF / Lifetime Pro discount code: "PHFRIENDS"] for launch week. I’d love to hear your brutally honest feedback: What’s your biggest friction point with Finder today, and what features would you like to see next in KoiFiles? Happy hunting, and enjoy a cleaner workspace! 🐟

Why I built KoiFiles: bringing an Explorer-style dual-pane file workbench to macOS

Hey Product Hunt!

While Finder works for basic daily tasks, organizing files across multiple projects, moving things back and forth, and handling archives on macOS often means juggling half a dozen messy windows and third-party tools.

We built [KoiFiles ( )](https://padap.cn/koifiles/en/) to bring a clean, lightweight, all-in-one file workbench to Apple Silicon:
