FreeFileSync 14.0

FreeFileSync 是一套免費開源的檔案同步工具，主要解決跨資料夾、跨裝置的檔案比對與備份問題。它最鮮明的特色是提供雙向同步與鏡像同步兩種模式，讓使用者能依照需求選擇單向備份或雙向合併，而且沒有同步檔案數量的限制，實際運作時僅受記憶體容量影響。這套軟體在 macOS 平台上的更新相當頻繁，屬於長期維護中的熱門選擇，雖然評分人數不多，但評價普遍不錯，在備份還原同類工具中算是穩健的實用選項。

這套工具適合需要定期備份大量檔案、或習慣手動控制同步流程的人，特別是在外接硬碟、NAS 或雲端資料夾之間維持檔案一致性時很實用。與 RAR、Disk Drill 等商業軟體相比，FreeFileSync 完全免費且開源，沒有試用期或功能限制，但介面僅提供英文，對不熟悉英文操作介面的使用者來說需要一些適應時間。macOS 版本與 Windows 版功能一致，若你原本就在多平台間切換使用，這套軟體可以維持相同的操作習慣。

FreeFileSync for macOS imposes no artificial limitations on how many files you can sync. Practically speaking, the only limiting factor for extremely large sync jobs is the amount of free memory available: For each 1 GB of RAM, FreeFileSync can synchronize roughly 1.7 million file pairs at a time.
