It's been a few years since I looked at it but I think the "HASH Examples in 4D" tech note includes a sample database that had as a proof of concept the ability to "find duplicate files on a hard drive" http://kb.4d.com/assetid=76130

Included with the Technical Note is a sample database that demonstrates using hash functions for encrypting passwords, file integrity, file fingerprinting, and finding duplicate files on a hard drive. -Tim ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
