    I'm trialing your software and have run into an issue that severely limits the functionality.

    I have a picture dump folder where I put photos before organizing into folders. The application is finding files in both the temp location and the final location. That is great, but it is finding the temp as the "Original" and there does not seem to be a choice to delete the original. With the current limitation, the application is not really worth it for me to purchase.

    As a feature request, it would be great to be able to create hierarchy rules. In my case, the folder structure temp should always be deleted if the file also exists in photos.

    Hello briands,

    Thank you for the feedback on the software. You are correct. Snoop-de-dupe currently does not allow you to delete the "original" file (actually it is the most recent file found in the duplicate list which does not give the option to be deleted). I will provide your feedback to our engineering group and see if we can get this fixed for the next release.

    Thanks! We always welcome product feedback and request for new features.

    This has been a big help in finding duplicate files to delete. I actually found more than I would have thought. I guess I should keep my files a little more organized.

  • jeff

    Great program. My only issue is I cant find a way to do bulk edits like hard link several files at once instead of one at a time. I have thousands of dupes and there is no way I could go through every file one at a time.
