Removal of duplicate photos in my dropbox photo library

Dropbox has become ubiquitous digital drawer of the netizens of the planet. The 8-step guide to remove the duplicates is tedious and ineffective. It's not an impossible job to equip Carousel (or Dropbox interface) with a tool to find and eradicate duplicates. Or point users to install third party tools to do this mundane job, if such utilities are indeed available. May it happen. Amen.

When I vew a photo ON MY MOBILE DEVICE via dropbox app does it upload again???  Is that why the exact same photos duplicate?

Or is it that each time I connect my phone to computer is it re-backing up/uploading all photos I have stored on my phone, even if they're already in Dropbox?

I know that if I download a photo to my phone and edit it, that it would upload again, but these are the EXACT SAME photo files with a number added to name (xxx1.jpg xxx2.jpeg)

One of the apps needs have built-in duplicate detection.

First they create the problem, then they sell you the solution. 

Hey if you able to access some other third party tools can use duplicate photos fixer app easily available on mac app store also. just run it and add your drop box folder in the software its automatically scan all duplicate photos and mark them to delete as per your choice you can delete them if found duplicates click here for <a href="http://www.duplicatephotofixer.com/Photofixer.aspx
">delete duplicate photos </a>

I am furious with Carousel and the stupidity of not being able to delete duplicates.  Which duplicate finder are you all using and does it really work?

Can someone help me understand how the duplicate photos are getting into DropBox so I can avoid future duplicates?

I love how dropbox is already using file hashes to save storage space, but somehow cannot use the same thing to detect exact duplications within the same drive.

A simple MD5 hash will just simply do this simple trick.

Please solve the "remove duplicates" problem.

I have to many pictures to be able to sync to my desktop. 

This is absolute insanity!  Deleting the dupes is not only tedious but an endless job!  As soon as I delete them, Dropbox starts uploading them again from my phone!  This not only chews up my mobile data, but it also maxes out my available space.  I have contacted Dropbox support about this, only to get useless, canned responses.  I have searched for solutions anywhere online, only to come up empty.

Could this "flaw" be 'by-design' to force basic users like me to pay for an upgrade to Pro?  Please, please, please FIX THIS already... I am a programmer and this is really NOT that hard to do!!
