Duplicate Image Finder
AllDup Duplicate Finder is the simplest way to look after the condition of your photo collection

Predefined search parameters quickly and easy find duplicate image files. When the scan is run any file that has a common image file extension will be analyzed and checked for duplicates. Afterwards the list of duplicate files can be sorted, exported to a CSV report, and acted upon (duplicate files can be deleted, renamed, moved, or copied).
An incredibly simple design comes with a number of adjustment options. You can select complete scan or specify folders for scanning. Additionally, you can ignore Exif metadata of JPEG files or scan compressed archives for duplicate image files.
Just some of the supported photo and graphics formats: GIF, JPG/JPEG, BMP, PNG, TIFF, ...
You can adjust file comparison criteria for the duplicate photo scan by a combination of the following search criteria: File Name, File Extension, File Size, File Content, Last Modified Date, Creation Date and File Attributes. File content comparison involves reading the file from the beginning to the end until a difference was found. The byte-by-byte method reads the entire contents of two files and checked for equality in parallel.
