  1. Giveaway Key:

    Use this key the provided one is not working

  2. Hy ,the provided license code is not working

  3. Very fast, accurate and lightweight. Very impressed.

  4. Setup file will not open, even when running as adminstrator. (Windows 11 home on HPOmen)

  5. Aww, that’s too bad – it crashes consistently and will not finish analyzing, and cannot pick up where it left off when it crashed, so why even start all over again just to crash again?

    It’s v1, so let’s wait for this to get to v4 or later to become as mature as the competition.

    Alternatives even like EaseUS DupFiles Cleaner which is currently on a 1-month trial, it’s also at v1, but did not crash on the same assignment.

    • Peter, I just ran a scan with this software just to try out. I didn’t face any of the issues you mentioned in your comment. In fact, I was able to find 232 GBs of data on my SSD in 34 mins.

      • The most important thing to me, other than
        – a program working always on it’s own,
        – and fixing anything inside itself to always work on it’s own is …

        … how support handles a problem.

        DupInOut contacted me and asked for a log,
        then replied that I should tell them what I was doing when it crashed
        ( I dunno, it crashed, and it’s not on the screen anymore ! ).

        This tells me that their log is useless,
        and that their program is not self-aware
        and not self-healing.

        On the one hand, not many programs are.

        On the other hand, given the robust competition,
        why would I spend a lot of time troubleshooting this,
        when other programs work in the same environment
        doing the same things
        just fine?

        All I can do is report back in,
        and let the programmers know
        they had at least one failure.

        I believe that’s a courtesy to the programmers.

        – – – – –


        I’m on Windows 7 x64 with 16 GB RAM
        It’s v1.1.2.1 located in:
        “C:\Program Files (x86)\DupInOut Duplicate Finder (Special Build for TickCoupon)\DupInOut.exe”
        And it has babies in:
        C:\Users\user\Local Settings\DupFilesUI
        C:\Users\user\Local Settings\DupInOut

        I don’t remember what directory I was scanning when it crashed.
        The program itself also does not remember what directory I was scanning when it crashed.
        It created 74 *.qlmc cache files that start with “qv4cdata%” in their contents, I presume these were file hashes in process, but there is no clue what files they might refer to.

        Maybe I’ll try it again when I have a chance, and get back to everyone.

        Thanks for letting us explore this and share.

      • There was a typo: I was able to scan 232 GBs of data
