Ultimate Duplicate Killer is a free, little and easy to use database program to manage large collection of files. I wrote it to manage my picture library.

Basically, it stores the CRC of all the files you have in a database (4 bytes per file) and when you scan some directories, it will delete (or move in a folder of your choice) all the files you already have. See the usage section for more information.

This program can delete files, so be sure of what you are doing, use at your own risk.
