Cause

Windows API（尤其是 Win32）将文件路径限制为 260 个字符 （MAX_PATH）。报告此错误的文件路径超过 260 个字符。此限制包括驱动器号、冒号、反斜杠、文件夹名称、文件名和文件扩展名。

Resolution

从 Windows 10 版本 1607、Server 2016 及更高版本开始，可以在作系统上启用长路径支持。

 

这可以使用目标 Windows VM 上的组策略或注册表更改来完成：

转到本地 Group Policy Editor → Computer Configuration → Administrative Templates → System → Filesystem。启用“Enable Win32 long paths”。

在 GPO 编辑器中启用 Win32 长路径

或设置注册表项：

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem]
"LongPathsEnabled"=dword:00000001
提醒：请咨询 Windows 系统管理员，以获取在目标虚拟机上启用 Win32 长路径的帮助。

Additional Information

如果启用了 Windows 重复数据消除功能，则可能会出现类似的错误：NVP vProxy：对于某些文件，Windows 虚拟机文件级恢复失败，并显示消息“无法恢复某些对象或安全属性”。
