Finder Not copying all selected files!

Over the years i have never made a solid folder structure now reaping the issues of that with over 50,000 photos, movies, graphics, and things i have made. I now started trying to cut down and remove all the duplicates. One thing i have noticed is how bad the finder is at doing its job.

So i searched for all the pictures througout all hard drives, i let it run for over an hour and it apparently had stopped at 10,000, so i scro to the bottom and more start loading i sit there untill about 40,149 appears to be as far as it will go. over 75% of those found are from application manuals within the apps directories... This isnt a problem, the problem is when i go to select all of those pictures to try and put them into one folder on one drive instead of scattered throughout all my drives, it coppies less than what i was told was being copied!

Okay so here is a snap of the search and the selected items, and then what its reconizing as its copying.

and because that probably really hard to see i made this

So it says its going to copy 9,865 files.... but in reality it only copies 8,191 thats 1,674 files un accounted for!?! and to prove it here are the copy results!

Which is some how 1 more than what the copy screen said but still thats 1,675 files unaccounted for... How am i supposed to trust my finder now that i know its this flawed? I need help i am literally going insane trying to organize this and my Mac being incapapble of doing so without threatinging the loss of precious family memories....

Im not the onlyone with this problem apparently... but it has still yet to be solved!
