Decloner: How to find & clean duplicates with same name but entirely different size

    So far Decloner has been a life saver for me!! I've found and separated 66GB of duplicate RAW and JPG images. Thank you!!

    When I look in the folders I have "decloned", I still see thousands of near-duplicate files - similar name (close enough for the SHA-1 cryptographic algorithm to determine if files are identical) but the file sizes are different. I think it's from photos being in iPhoto and Aperture - both apps have wound up giving me different file sizes. Here's an example...

    IMG_4420 - 2011-01-09 at 19-27-51 (1).JPG (4MB)
    IMG_4420 - 2011-01-09 at 19-27-51.jpg (7MB)
    IMG_4421 - 2011-01-09 at 19-27-51 (1).JPG (4MB)
    IMG_4421 - 2011-01-09 at 19-27-51.jpg (7MB)

    Decloner isn't seeing these as duplicates.

    Is there a filter or command that I can use to find and remove the smaller (4MB) duplicates from the example above?

    Many thanks!

    Hi,
    I like very much decloner the way it does the job, but
    1 / Now it is cleaning on base of the document itself . That is ok
    2 / I would like to have the possibility of second choice to clean on base of the same names of the documents
    I hope my writing here is clear ?
    Thanks anyway for that good prog

    Decloner only detects exact duplicates, and it does so by computing SHA-1 hash of the contents. Any other way of guessing duplicates would be asking for trouble (data loss), and I have no plans to implement it at present. Sorry.
