Comparing two directories

[Lee Underwood]

I have a directory with graphics in it, i.e., Graphics/example. In order to include it in the shortcuts listing I renamed it, i.e., Graphics/Graphics-example  (or at least that is what I thought I had done.). However, I somehow created a new directory with the files copied to it. Over time, w/o noticing, I have saved files to both sub-directories. How can I compare the two directories to find any different files?
