Thumbnail Popup Menu - Rename...

 

 

This option will prompt for a new file name for each selected file, and rename it accordingly. You cannot move a file to a different folder with this option; use File | Move instead.

 

Note: If the file was pasted or scanned (rather than loaded from disk), this option is unavailable.
