Clone Tools gives a great overview of duplicate files and folders

Clone Tools helps you find identical files on your computer and displays the files in a way that makes it easy to identify which files to delete and which to save. To make this as easy as possible Clone Tools not only works with files but also with folders. If a folder contains duplicate files it will be compared to other folders that also contains duplicate. If two folders shares duplicate files, they will be listed so you can easily compare their contents in the Twin Browser. This simplifies the task of deciding which of the duplicates to keep and which to delete. Clone Tools also provides a powerful filter option that helps you find the folder that contains files that are relevant and ignore the rest. There are also effective tools that helps you purge duplicate content from folders or merge folders, as well as all the usual file handling abilities (copy, delete ,cut and paste).
