Recover RDB files from My Book

My desktop  PC crashed.  I opened  My Book Premium ES Edition external drive on my laptop and could not find any regular backup files.  There were folders but nothing inside except the generic PC photos; not mine.

A file (?) collection for the past 5 years  were in the .RDB file type. I do not have any Retrospective software on the laptop.  Help!!
