xdelta: Windows 下大文件比较(diff/patch)工具

Unix/Linux 系统下的 diff 和 patch 工具真的非常好用!
但是在 Windows 下似乎没有很好的替代工具(装 MinGW 方式除外)。

如果只是比较小文件,其实 Windows 下不缺工具,Beyond Compare、DiffMerge、UltraCompare,Tortoise SVN 也带有一个文件比对工具。
但是如果要对比两个 2G 的文件,90% 的工具都要废了,貌似他们都喜欢把要比对的文件完全加载到内存中,然后做可视化的比对。

最后找到的 xdelta 这个工具可以满足我的要求,项目地址:
