FreeFileSync 14.8

FreeFileSync 是一套開源且持續活躍維護的檔案同步與備份工具，主要解決不同位置之間檔案比對與同步的問題，例如本機硬碟、外接磁碟、雲端資料夾或網路磁碟機之間的資料一致性。它與傳統備份軟體最大的不同在於，核心是「同步」而非「壓縮打包」，支援雙向同步與鏡像同步，能讓兩端資料保持最新狀態，或單向複製成鏡像。在同類工具中，它屬於評價普遍不錯的小眾選擇，更新頻率相當穩定，但整體知名度與使用者數量仍不及主流壓縮備份軟體。

這套軟體適合需要頻繁維持多處資料一致性的使用者，例如同時使用桌機與筆電、外接硬碟做工作檔案同步，或需要定期將重要資料鏡像到另一顆硬碟的人。與 WinRAR 這類壓縮備份工具相比，FreeFileSync 不做壓縮，而是直接複製檔案結構，取捨在於同步速度快、差異比對精確，但沒有單一壓縮檔的封存便利性。授權為開源免費，Windows 與 macOS 都有版本，但介面僅提供英文，不熟悉英文操作介面的使用者需要稍微適應，且目前沒有內建中文語系。
