This code finds duplicate files in a specified set of folders. It is written in PHP and includes some filtering options via the query string. It is free for non-commercial use; a fee may be required for commercial use (see the code itself for details).The code consists of one PHP file.

Usage notes, examples, copyright, and license are contained within the php file itself.

My thanks go to the PHP Group (http://php.net/credits.php) and to Zach Saw (http://www.zachsaw.com/) for his QuickPHP server.

Please feel free to improve this code and send me the changes. Thank you! - L. Murphy
