Powershell用父文件夾名稱替換文件名而不更改文件結尾

Question

我有一個父文件夾，其中包含1000多個1級嵌套文件夾，每個文件夾中有成千上萬個文本文件：

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

我需要能夠使用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

有沒有一種方法可以在Windows Server 2012 PowerShell中進行

提前謝謝你。
