Dup Detector v1.1 (freeware version)
Searches your image collection for
duplicate and near duplicate images.
It creates a data file by opening and
reading image pixel data for each
image in your collection. It then
finds duplicates by % match and
displays matching pairs from a log file.
Supports 9 image file formats
(jpg,bmp,png,tif,pcx,tga,wmf,emf,psp).
This freeware version requires all
images to be in one folder (or subfolders).
PhotoBatch version allows use of an
image list of folders or files.
Our Review: This is a very useful program - especially if you maintain large collections of images. Dup Detector performs searches on archives of images and detects duplicate images based not on the filename but on the actual image content. A sliding scale allows you to set the sensitivity that Dup Detector will use in determining a match and at the conclusion of the search you can view all suspect files in a pair of large thumbnail viewers. Dup Detector can also create log files (that can optionally contain image thumbnails) should you wish to keep a record of changes to your collection. The process of finding and deleting duplicates is very very easy using this program.
