Files - Duplicate Checkers (11)

CloneSpy v3.41 Updated

  • 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 choose between a 32 or 64-bit version of CloneSpy.

Stealth: ? Yes
Unicode support: Yes

How to extract: Download the installer and select 'portable version' at installation type. Launch CloneSpy.exe.

What's new? Added:
  • Files and folders that are ignored during scanning can now be logged (see Logging page of the Options window).
  • A new option remembers size and position of the Add folder window (see Priority page of the Options window).
  • The new command line option -s allows for silent scans (see the help file for details).
  • A message box now explains the Delete all (!) option on the Time + Size page of the Options window when that option is selected.
Modified:
  • Removed the entry Programme from the default folder ignore list (see Folders page of the Options window).
Fixed:
  • Hitting the space bar while a scan is ongoing no longer closes the scan progress window.
  • The context help now works for the edit box in the Insert mask window.
  • Corrected typo (spacing) in the Mode drop-down box of the Main window.

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.

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.

Working as "freeware" for me :) very nice software does all I want and more thanks for job well done.

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.

@webfork

Appreciate your tightening of Antidupl.NET functional capabilities description, particularly in reference
to the product remarkable customizable divergence threshold and its image differences highlighting ability.

Russian users are reporting some issues with AntiDupl v2.3.9
"version 2.3.9 # 7 is not working"

I'll gladly stick with v2.3.8 till the dust settles...;-)

Bytessence DuplicateFinder v1.3.0

webfork on 15 Jun 2015
  • 1MB (uncompressed)
  • Released on 7 Oct 2011
  • Suggested by Wolfghost

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).

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

If you can reproduce the crash, please enable logging from the Settings dialog. The error handler should catch the exception and will write it in the log. You can send the log to the support e-mail and I'll try to fix the problem. Thanks and don't hesitate to contact me if you find 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).

webfork on 2013-05-10 01:51

Getting intermittent errors with the website. Softpedia link: http://www.softpedia.com/get/PORTABLE-SOFTWARE/System/File-management/Bytessence-DuplicateFinder-Portable.shtml

Dup Detector v3.3.0.2

webfork on 17 Dec 2015
  • 2MB (uncompressed)
  • Released on 7 Aug 2011
  • Suggested by Kongu Tamil

Dup Detector finds duplicate or near-duplicate images by comparing image pixel data. As large image collections can over time pull in duplicates with different file sizes and different names, this program helps track those down and save disk space.

Note: main website down, linking to archive.org

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 temporary folder
  2. Move the contents of {app} to a folder of your choice
  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.

AlephX on 2007-02-04 23:45

I had a DL error... anyway it´s possible to find it even at
