AllDup removes duplicate files from one or multiple directories and includes a preview function using Windows own tools (IE, MediaPlayer and WordPad). Can find duplicates by file name, file extension, file content, file dates, file attributes. The program can also help identify and remove music and or image files that are not only slightly different.
Multiple files, directories, and drives can all be scanned, as well as ZIP or RAR archives (with an optional file size limit), along with filters for file types and/or folders.

It seems that with v4.2.0 it now phone home no matter what on every startup, 4.1.8 didn't do this and yes, the option "Check for updates on startup" is disabled. |

Absolutely excellent program that saved a ton of room on my hard drive, clearing out duplicates as well as several multiple-size images from an earlier effort to compress some really big photos. The best part is how it automatically sees two photos that are already very similar and helps you pick the better one to archive. There were only one or two false-positives in a batch of hundreds (a concert picture somehow got paired with a painting of Mozart). |
AntiDupl.NET is a tool to search for and delete identical or very similar pictures. Includes a customizable difference threshold and can highlight image differences, supporting JPEG, GIF, TIFF, BMP, PNG, EMF, WMF, EXIF, ICON, JP2, PSD, DDS, TGA and WEBP files.
The program can also detect image defects.

I thought my similar image analysis program of choice was more than adequate but this program is remarkably good. The program works really fast on a TON of images and the change detection is very useful.

Russian users are reporting some issues with AntiDupl v2.3.9 |
CloneSpy can help you free up hard drive space by detecting and removing duplicate files with exactly the same contents regardless of their name, date, time, or location. Also, CloneSpy is able to find files that are not exactly identical, but have the same file name. This can be an issue for example if you have different versions of a file and you want to find and remove the older versions. CloneSpy is able to find zero-byte files.
Note: The installer now allows you to choose between a 32 or 64-bit version of CloneSpy.

A lot of people here trying to delete multiples of the same image - I just wanted to give a shout out to Dup Detector, which is a great piece of software that does exactly that.

Oh awesome. Well, it's still great software - it does one thing & does it very well. |
Bytessence DuplicateFinder (BDF) detects all the cloned files that you might have on your computer. These files, in addition to taking up valuable space, can increase antivirus scan time, slow defragmentation and searches, and make it more difficult to organize your files.
The program employs optimized detection system and file filters to reduce scanning time. Detected files can be removed in no time with the help of the automatic file selector and the predefined set of actions (copying, moving or recycling).
Note: Website is offline, switched to Archive.org

Hello! I am the developer behind BDF. I just released a new version of the program (1.3) which fixes some annoying bugs.

Might be my new favorite duplicate finding program on the site next to DoubleKiller http://www.portablefreeware.com/index.php?id=136 (and certainly much easier to use).
