I have 1000s of duplicate photos in many different directories on many different hard disks. My home server has my primary copy of pictures. I want to consolidate and make sure I'm not missing any pictures; is there a utility out there I can use where I give i two directories - a source and destination, and it will show files in the source which are not present in any subdirectories in the destination?

I run Linux, Windows and OS X but my preference is a graphical tool for Windows or Mac.

  • Welcome to Software Recommendations! There are command-line tools that run on Solaris, and you need to pay for the license. Interested? :D If not: please edit your question and specify what OS the software shall run on, and how much you'd be willing to spend if it comes to paid solutions, whether you need a GUI. Be welcome to take a look at our quiestion quality guide for other improvements; the better you specify your requirements, the better answers can match them. Thanks!

I haven't tried it but it looks like Nirsoft SearchMyFiles might be what you are looking for. You can select "Non-Duplicates Search" in the Search Mode dropdown.
