How can I deal with duplicate files

I know this is late, but there is a program called "Alldup" that is for donation or free if you need it to be.  It's a duplicate image / file finder.  I don't know how, but I ended up with HUNDREDS OF THOUSANDS of duplicates of my photos.  Some were different sizes, new names, I have no idea what happened.  But I let alldup run overnight and it showed me all the duplicates.  I choose to keep the largest file by size and automatically delete the smaller duplicates.  It took all night for the program to run, but it works like a charm.

I won't both going into why I have a large number of duplicates, but the number is currently 17,000.  I found an add on app to Lightroom that appears to do a good job of finding duplicates.  It creates a smart collection called duplicates.  The method I am using is to 1) find the original I want to keep and clear the duplicate keyword.  Easy enough.  2) I have to go to the go to the folder in the library so I can delete it.  I tried doing a right click and remove from the smart collection and it won;t let me do that.  

Is there a faster way I can speed up this process?
