Using Finder or Explorer, go to the folder containing the catalog you want to delete.
Delete the catalog (*.LrCat) and the one or more preview folders (*preview.LrData) that matches the catalog.
Make sure you are deleting the correct files as there is no "undo" in many cases.
Thanks. What is the Lightroom Catalog above? I had the lightroom CC on my computer but I am not using it. Is the lightroom catalog the one for the Lightroom CC? Can I take this out also?
I want to clean up lightroom 5. I used a while back and started several catalogs.

Which Lightroom version are you going to use now?
Lightroomcatalog.lrcat in the screenshot is Lightroom CC catalog.
If you are not using any of those two catalog(Lightroomcatalog and Lightroom5catalog) , You can delete them.
I Just upgraded to Lightroom 6 standalone (not creative cloud).
Both Lightroom CC/6 share same catalog name.
So you should keep the Lightroomcatalog and delete the older Lightroom 5 catalog.
Thank you very much. Now I can start over in the correct way (organized!).
