Find duplicate photos with Find.Same.Images.OK for Windows

Find.Same.Images.OK is a free portable software program for Microsoft's Windows operating system to find duplicate photos (and any other image dupes) quickly.

Unless you are very careful when it comes to download images or transferring images from digital cameras, smartphones and other devices, you will end up with duplicate images eventually.

Sometimes, that is desired, e.g. for backup purposes. At other times, it may cause issues such as lower than expected free disk space on drives or productivity issues when it comes to finding photos.

Find.Same.Images.OK is a duplicate image finder for Windows. It falls in the same category of applications such as Double File Scanner, AllDup, VisiPics, or AntiDupl which may also be used to find dupes and deal with them.


You can run Find.Same.Images.OK after you have extracted the archive it is supplied as. The program's interface looks convoluted; it is set up by default to scan then entire c: drive for duplicate images.

A click on the browse button or the add button provides an option to scan custom and multiple locations. You could run a scan on drive c: and d:, or two different folders on a single drive.

The scan time depends largely on the size of the folder, the structure, and the performance of the PC system. A scan of c: may take quite a bit of time on its own but if you add another drive to it, it will extend that time even further.

Scan options may extend the scanning time further; you may include checks for rotated, flipped or negative images, and change the default "performance & quality balance" setting to "quality" or "performance" only.

Find.Same.Images.OK displays hits in the interface and displays a preview of the selected match pair to add a visual component to the process.

Each pair is listed with its full path, size, similarity and ratio information. Similarity defines how similar a pair of images is; you may use filters to limit the list of results. The default filter displays all image pairs that are at least 90% similar.

Images may not be 100% duplicates if they have a different size or format among other things. The application uses an algorithm to determine similarity by creating graphic signatures; this algorithm finds duplicates if images are rotated, mirrored, or altered in other ways.

You can deal with duplicate photos on a case-by-case basis or have the program process all duplicates in one swift operation; it is recommended to go through the listing to make sure that there are not any false positives.

Duplicates may be moved or copied, or put in the Recycle Bin. Find.Same.Images.OK may pick the better image for you

Closing Words and Verdict

Find.Same.Images.OK is a powerful tool for Windows to find duplicate photos and other images. It does not just check whether images are 100% dupes but finds images that are similar to a certain degree as well.

Now You: Do you use programs to find duplicate files?

    Clonespy is pretty potent tool – albeit a bit complex (which is what gives it such power).

  2. Luis said on January 5, 2019 at 3:34 pm

    Clonespy is the best in this category and FREE!

    Been using VisiPics for years. User friendly, great Help file, just the right amount of options.

    I have enjoyed using “Awesome Duplicate Photo Finder” for years. How can you go wrong with a name like that ?

    Find it here:

    I see my favorite hasn’t been mentioned in the comments yet. It’s a very simple, tiny app called AntiDupl that does the job very well.

    This is not a good program after main dealings with this program now for a while, I have to conclude. This because you have to not only ferry secure to compare pictures especially pictures who are taken close after each other with not a significant difference.
    But the real big problem begins when you want to upgrade this program.
    The upgrade to a newer version is always going wrong. After the update, the program works not as it should be working(Correctly) bust mostly the program does not work at all. When you’re trying to uninstall and after that clean, the registry, etc and then install a newer version forget it the program will not work again.
    Never could after a reinstall make a program work again in 40 years. But this program did. Its a shame because the idea behind the program is really great.

    Not a specific program, just Directory Opus.

      This requires the Pro version of Directory Opus, though.

        …but for your malchance it was the end of the 40% discount today:

        Yes, but better than “Duplicate Cleaner PRO” that you are promoting just above.

        @ Anon

        I’m not “promoting” anything. Just sharing info that might be helpful to others. Let me introduce you to this nice concept, which you seem not to be aware of, despite its usefulness in social relations.

        If you wanted to be helpful too, instead of snarky and useless, you wouldn’t inform Ghacks readers of an expired promotion. And you wouldn’t just say it’s better. You’d explain why it’s better, in your opinion. The word opinion is important here.

    The best free dedup program I’ve been able to find, up to now, is Duplicate Cleaner. It has a special image mode in the paid-for version.

    I use the duplicate image finder that is one of the built-in features of the very well-known XnView image viewer. As far as I can see (judging from this review) XnView does offer the very same or even better options, such as setting unlimited locations for gathering images to compare, fine-tuning the similarity percentage, etc.

    I love Ghacks and all of Martin’s hard work, I really do, but sometimes (like now) I wonder what’s the point of reviewing some minor “new” software that in fact appears to offer nothing new.

      As it turns out, I was looking for an app like this, so both the reviews are helpful, as well as comments like yours suggesting alternatives.

  10. Belga said on January 2, 2019 at 1:24 pm

    I was using DupeGuru (not maintain anymore).
    Same scan (2700 images) with it shows 12 correct similarities against 25 with “Find.Same.Images.OK”.
    One finds what the other does not and vice versa.
    In conclusion, use at least 2 different programs.
    Thanks for the tip Martin!
