DupeNuker

Detect and Delete Duplicate Files

Download for Windows Vista/XP
Download for Mac OSX

DupeNuker uses the CRC32 algorithm to create very small "fingerprints" that identify a file. The purpose of this is to automatically identify duplicate files and delete them. What makes DupeNuker unique is that you don't need to have the original files in order to detect duplicates. This method is ideal for removing spam from files that you download from newsgroups. Even after you throw away the files, DupeNuker keeps their fingerprints in its database, and if you download them again, it will identify them and delete them.

Spammers morph everything about their posts: especially their email addresses, subjects, and filenames, so that it is impossible to avoid downloading thier files. But with DupeNuker, you won't have to sort them out manually. If you use JpegJet with DupeNuker, you won't even have to see them! DupeNuker is built into JpegJet, however you can use DupeNuker with any newsgroup-downloading program such as NewzScape, or simply to look for duplicate files in your collection.

Be sure to read the Help Page to learn how to use DupeNuker with JpegJet, NewzScape, or any other downloading program.
