   I'm looking for a way to change all the extensions in a folder AND its   
   subfolders. My batch skills have dropped over the decades from novice to   
   almost non-existent so I'd much appreciate some help please.   
      
   I do have the excellent tool Bulk Rename Utility but that applies   
   filename changes at single folder level. My parent folder has scores of   
   children (and quite a few grandchildren), so that would be tedious and   
   time consuming.   
      
   Specifically, I want all the *.ino files within say c:\docs\xyz to   
   become *.txt.   
      
   If it matters, I'm using Win 10 Pro.
