Powershell用父文件夹名替换文件名而不更改文件结尾

Question

我有一个父文件夹，每个文件夹中有超过1000个1级嵌套文件夹和数千个文本文件：

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中执行此操作

提前谢谢你。
