Is there a quick way to find duplicate files in robohelp

Hi Guys

A bunch of new menu options appeared at the dusty configuration / admin end of the menu system of the product for which I am producing online help, recently.

So I cursed the gods of Agile, fired up the Espresso machine and quickly created a hundred or so new help topics into which I could add the appropriate field / description information.

Subsequently I realised a lot of these "new" menu options were actually pre-existing options which have been dragged and dropped from other areas of the system - and for which I had already written help topics. So I now have files with the same name scattered around the various folders, which I have to find.

Obviously I have to identify those files that have been duplicated before moving the originals to the new location and deleting the newly created, empty topic files.

This task would be a lot easier if there was a way of finding which files have duplicate names and where the originals are located on the system. 

Is there a report i can run to find topic files with the same file name? For example two files called "Create client" or "System parameters". Or is there some other whizzy way of doing this..

While I'm here, is there a way of locating "Unused" files - as many superseded graphics files are floating around the system too. (Most of those have been renamed with the prefix "OLD" if thats any help)

Once again thanks in advance for your time and wisdom, comrades..
