Files - Duplicate Checkers (11)

I thought my similar image analysis program of choice was more than adequate but this program is remarkably good. The program works really fast on a TON of images and the change detection is very useful.

@webfork

Appreciate your tightening of Antidupl.NET functional capabilities description, particularly in reference
to the product remarkable customizable divergence threshold and its image differences highlighting ability.

Russian users are reporting some issues with AntiDupl v2.3.9
"version 2.3.9 # 7 is not working"

I'll gladly stick with v2.3.8 till the dust settles...;-)

A lot of people here trying to delete multiples of the same image - I just wanted to give a shout out to Dup Detector, which is a great piece of software that does exactly that.

Dup Detector doesn't just do file-size/checksum analysis, it actually analyzes the images to find similarities. E.g. one could be black & white and the other can be color, or one can be watermarked, or one could be taken 2 seconds later because someone blinked & it'll find both and display them to you and ask which one you want to delete or if you want to keep both. You can choose how strict it is in its matching algorithm - 100% mach, 95% match etc.

You can even have it set up to automatically select which one to delete based on rules - e.g. the smaller one. Then you just approve the selection by hitting the space bar, or you can just let it do its thing automatically, or you can go full-manual mode and click the image you want to delete. Super fast way to delete duplicates and easy to use. I've used it professionally to manage large image catalogs that had a lot of duplicates of different sizes.

Unfortunately, it's not portable.

The latest version I have is 3.3.02 from July 8, 2011. You can get an earlier version from rareware.

Oh awesome. Well, it's still great software - it does one thing & does it very well.

Hello! I am the developer behind BDF. I just released a new version of the program (1.3) which fixes some annoying bugs.

If you can reproduce the crash, please enable logging from the Settings dialog. The error handler should catch the exception and will write it in the log. You can send the log to the support e-mail and I'll try to fix the problem. Thanks and don't hesitate to contact me if you find bugs.

Might be my new favorite duplicate finding program on the site next to DoubleKiller http://www.portablefreeware.com/index.php?id=136 (and certainly much easier to use).

Getting intermittent errors with the website. Softpedia link: http://www.softpedia.com/get/PORTABLE-SOFTWARE/System/File-management/Bytessence-DuplicateFinder-Portable.shtml

Link no longer works! Sad because this is exactly the type of program i was looking for.

Since the license says it is freely distributable, I have added a direct download link for those of you who still want it.

I had a DL error... anyway it´s possible to find it even at
