【问题描述】：

我有一个父文件夹，其中包含 1000 多个 1 级嵌套文件夹和每个文件夹内的数千个文本文件：

Parent folder ==> Folder1 ==> File1.txt
Parent folder ==> Folder1 ==> File2.txt
Parent folder ==> Folder1 ==> File3.txt
Parent folder ==> Folder2 ==> File1.txt
Parent folder ==> Folder2 ==> File2.txt
Parent folder ==> Folder2 ==> File3.txt
Parent folder ==> Folder3 ==> File1.txt
Parent folder ==> Folder3 ==> File2.txt
Parent folder ==> Folder3 ==> File3.txt

我需要能够使用 PowerShell 重命名文件，如下所示：

Parent folder ==> Folder1 ==> Folder1_File1.txt
Parent folder ==> Folder1 ==> Folder1_File2.txt
Parent folder ==> Folder1 ==> Folder1_File3.txt
Parent folder ==> Folder2 ==> Folder2_File1.txt
Parent folder ==> Folder2 ==> Folder2_File2.txt
Parent folder ==> Folder2 ==> Folder2_File3.txt
Parent folder ==> Folder3 ==> Folder3_File1.txt
Parent folder ==> Folder3 ==> Folder3_File2.txt
Parent folder ==> Folder3 ==> Folder3_File3.txt

有没有办法在 PowerShell、Windows Server 2012 中做到这一点

提前谢谢你。

非常感谢 Anthony 的快速回复，我是否需要进行任何循环，或者这是否适用于父文件夹下的所有文件夹和文件？
我刚刚添加了-directory。这将适用于直接在“文件夹”内的文件夹。创建您的示例文件夹结构以对其进行测试。
