Quote: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.
