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.

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...;-)

CloneSpy v3.43

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.

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

Modified:
  • Hard links and shortcuts are now created before the file to be replaced is deleted (see Deletion page of the Options window).
  • Leftover files are now deleted at the end of a scan to prevent deletion conflicts (see Deletion page of the Options 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.

Would be nice if it had an option to not search subfolders.

Hinesmdc on 2015-06-05 02:51

@kiwichick It does!

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).

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).
