Renaming multiple files at once
 

Help!

Does anyone know how to re-name image files at once?
Let's say I have 3 files, called ROB, LOB and BOB.
Let's say I want to add the date to the end of each of these so they read as

ROB_11.12.14
LOB_11.12.14
BOB_11.12.14

Is there a way to highlight them all and rename the end of each file without having to individually click on them and click rename?

I assume these are saved files located somewhere on a HDD/network share?

Also, which OS?

Never mind. I see you had the issue resolved in one of your double-posting things.

I downloaded some program called ReNamer Lite and it is like the honey-badger of ReNaming programs.
