Comparing folders

Can I use Opus Light to compare folders? The Help guide shows how to do this very clearly, but the menus don't show in my installation. I have lots of duplicate folders of images. Is there a function that will compare two folders, identify those images that are the same and those that are different? So far all I have been able to do is to open the two folders side by side and then compare visually. Which is too slow.
Thank you for your help.
