问题 I am able to batch rename files in a working directory by using: Dir | %{Rename-Item $_ -NewName ("0{0}.wav" -f $nr++)} However I want the file rename to start at something other than zero.

问题 I have been trying to rename each txt file in a folder with the filename $New-Guid .txt, so they should all have unique names.
