Renaming files on my PC all at once without external program

Question

I want to rename several files at once. For example, change _ to - . I don't want to install and external program and want to know if there is an inbuilt feature. I am running Windows 10.

Answer 1

A VBS Script File should work.

Set objFso = CreateObject("Scripting.FileSystemObject")
Set Folder = objFSO.GetFolder("File Location")

For Each File In Folder.Files
    sNewFile = File.Name
    sNewFile = Replace(sNewFile,"ReplaceThis","WithThis")
    if (sNewFile<>File.Name) then 
        File.Move(File.ParentFolder+"\"+sNewFile)
    end if

Next

Save it as .vbs and run it.
