Code Compare 5.2.170

Code Compare 是 Devart 推出的免費檔案比對工具，主要解決開發者在比對原始碼、合併檔案或資料夾差異時的繁瑣流程。它同時提供獨立視窗與 Visual Studio 擴充功能兩種使用方式，並能整合 TFS、SVN、Git、Mercurial、Perforce 等主流版本控制系統，讓比對動作直接融入日常開發環境。這套工具自 2014 年起持續維護，更新頻率不算密集，但評價普遍不錯，在同類開發工具中屬於小眾但穩定的選擇。

這套軟體適合需要頻繁進行程式碼審查、分支合併或版本差異確認的開發者，尤其是已經在使用 Visual Studio 或上述版本控制系統的團隊。免費版已涵蓋多數比對需求，若需要三向合併或結構化比對等進階功能，則要考慮付費的 Pro 版。與其他比對工具相比，它的優勢在於與開發環境的整合深度，但僅支援 Windows 平台且介面為英文，非英文使用者需要稍微適應。若只是偶爾比對文件，免安裝的輕量替代方案可能更省事。
