Editor: Dup Detector finds duplicate and near duplicate images by opening and reading image pixel data. Large collections and large image file sizes can slow Dup Detector but it works well running in the background. Large image collections often are filled with duplicate images under different names. Use Dup Detector to clean them.
DupDetector reads 9 image file types from a folder or its subfolders or from an image list.
Version 3.0 has many improvements including automatic and semi-auto delete modes, shortcut keys for scrolling through matching image pairs, and more Precision in the matching Algorithm. Version 2.0 datafiles are not compatible with this version, just rebuild them.
