How do I use cmd prompt to change all files in all subfolders?

[BlackScarlet]

I know that I can easily change the filetype of all files within a Windows folder by opening an elevated command prompt within that folder and typing "ren * *.jpg" or whatever other filetype I want to change it to, but how can I modify this command so that it renames all files in the current folder, but ALSO, in all subfolders?

I found this info---

I put the link in a folder & zipped it.
Otherwise the automated spam filter here probably would not allow it.
