Duper. Kind of useful freeware for locating duplicate files like digital photos methinks.
Duper scans directories for identical files, allows you to easily locate and delete duplicates wasting hard disk space. The latest version is 20041011 (revision 296). The philosophy behind Duper is to be fast, free and small…Duper first scans all file sizes. If any two file sizes are identical, an MD5 sum is computed for each file and then used to determine if they are identical. After scanning, it allows you to browse through the duplicates found and select those you wish to delete.
