Wish I had this app sooner

Follow the directions and there will be nothing but success. Pro version worth the few extra bucks (it was on sale when I purchased). Pro version lets you start with exact duplicates (safe start) then progress to duplicates by another name and resolution (trickier). Auto mark with default rules keeps the higher res image with the most meta data. :) :)
