您可以使用 WMI ,检查 CIM_DataFile 和 CIM_Directory 类。
一些注意事项
1.首先您必须在客户端机器上启用 wmi 远程访问。阅读这些文章,了解如何做到这一点以及 Windows 版本 Connecting to WMI on a Remote Computer、Securing a Remote WMI Connection 之间的区别。
2.始终必须使用过滤器(Where 条件)来限制这些 WMI 类的结果。
3.始终必须使用Drive 字段作为条件,因为这些类返回所有驱动器的文件。
4.Wmi 将\(反斜杠)字符解释为保留符号,因此您必须对该字符进行转义以避免WQL 语句出现问题。
