Dup Detector finds duplicate or near duplicate images by comparing image pixel data. Large image collections are often infested with duplicate images under different names.

Category:
System Requirements: WinXP / Vista / Win7 / Win8
Writes settings to: Windows registry. It was a tough call, but I finally decided to accepted it as portable because it is probably not something that you will run that regularly. And when you run the program on a different machine, a few parameters will need to be adjusted anyway.
Stealth: ? No. A yaP configuration file to make Dup Detector portable and stealth is available at http://rolandtoth.hu/yaP/#examples
License: Freeware
How to extract:
  1. Download the installer and extract to a folder of your choice
  2. The application files are in the {app} folder
  3. Launch DupDetector.exe

Link no longer works! Sad because this is exactly the type of program i was looking for.

Andrew Lee on 2006-07-26 23:55

Since the license says it is freely distributable, I have added a direct download link for those of you who still want it.

CloneSpy v3.2 Updated

Checker on 31 Mar 2015
  • 6MB (uncompressed)
  • Released on 30 Mar 2015
  • Suggested by Fluffy

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 select between a 32-bit and a 64-bit version of CloneSpy.

Category:
System Requirements: WinXP / Vista / Win7 / Win8
Writes settings to: Application Folder
Stealth: ? Yes
Unicode support: Yes
License: Freeware
How to extract: Download the installer and select 'portable version' at installation type. Launch CloneSpy.exe.
What's new? Added:
  • The installer now allows you to select between a 32-bit and a 64-bit version of CloneSpy.
  • If you push the "Delete all marked files" button in the Zero length files window or Single duplicates window without first marking any file then an explanation is given on how to mark files.
Modified:
  • Optimized the memory management so that now more of the available memory can be used.
  • Optimized the structure of the checksum database leading to the effect that your database needs to be rebuilt (previously cached checksums will be recreated).
  • If you scan a large number of files then the percentages in the scan progress window now have decimal places.
  • Opening and closing a large number of categories in the All duplicates window are now faster.
  • Marking a large number of files in the All duplicates window is now faster.
  • The upper limit for the size of scanned files is now deactivated by default (see Time + Size page of the Options window).
Fixed:
  • If you have a large checksum database then CloneSpy no longer freezes for some time when you open the Options window.
  • The Options window no longer freezes while the checksum database is being cleaned up (see Database page of the Options window).
  • In the Options, if "Make new file" or "Replace file" is selected then the corresponding file name may no longer be erased.
  • The Single duplicates window no longer shows files that were already deleted manually by the user during the scan.
  • If CloneSpy is ran from the installer then it now runs with user privileges.
  • Corrected the original file name in the version information of the installer.

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.

Dup Detector doesn't just do file-size/checksum analysis, it actually analyzes the images to find similarities. E.g. one could be black & white and the other can be color, or one can be watermarked, or one could be taken 2 seconds later because someone blinked & it'll find both and display them to you and ask which one you want to delete or if you want to keep both. You can choose how strict it is in its matching algorithm - 100% mach, 95% match etc.

You can even have it set up to automatically select which one to delete based on rules - e.g. the smaller one. Then you just approve the selection by hitting the space bar, or you can just let it do its thing automatically, or you can go full-manual mode and click the image you want to delete. Super fast way to delete duplicates and easy to use. I've used it professionally to manage large image catalogs that had a lot of duplicates of different sizes.

Unfortunately, it's not portable.

The latest version I have is 3.3.02 from July 8, 2011. You can get an earlier version from rareware.

It's not freeware. It's a time-limited demo.

Onesimus Prime on 2011-01-09 02:18

At least three places on their site, they call it freeware, including the phrase "Freeware for private and commercial use" (http://www.alldup.de/en_alldup.htm)
On the other hand AllSync, from the same company, is time-limited shareware--perhaps Lee got the two confused?

webfork on 2013-02-16 20:12

@Prime: Unknown. Anyway, just rechecked the status and the current license info is correct.

Simple Duplicate Finder v1.2.0.3 Updated

Midas on 5 Mar 2015

Simple Duplicate Finder helps track down similar files either to delete extras and save space or to compare versions. While most duplicate-searching programs are looking for exact copies, SDF uses a Percentage Search, allowing you to adjust the percentage difference required for a file to be considered a duplicate. Once scanned, the program will display the number of bytes which differ as well as the specific percentage match between files.

This is useful for example with metadata: when Windows Image Import tool downloads pictures from your digital camera, additional XML data is inserted into the images and video files, including a timestamp of when the image was downloaded to the computer. Although the image is identical in every way to its original, the file will appear as unique. SDF can detect these files and help remove them.

Note: main site appears to be down, switched to archive.org
