Sui Generis

If you keep photographs on your computer, you probably have hundreds of duplicates scattered among the many folders you use to organize them. Sui Generis scans files and folders, and organizes them into "clusters" of duplicate files. You can then designate duplicates to move into a "pen" directory, from which you may delete them, archive them or whatever. Sui Generis includes features to let you quickly select duplicates to put in the pen, as well as a way to preview files before you move them. It also has a plug-in interface through which you can add preview tools for specific file types. I hope it will be useful to you.
