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.

Simple Duplicate Finder v1.2.0.3 - link date 20-FEB-2012
Just re-discovered this antediluvian gem of a dups finder...;-)

What's not to like ?

• Terse, elegant, skillfully crafted GUI
• Option for similitude percentage match
• Filter for file extension
• Duplicate entries results neatly listed as offset to the stem file
• Stunningly fast execution (files CRC used as match criteria)
• Tiny footprint (117KB exe)
   Leanest of TPFC's "Duplicate Checkers" current 11 entries

Oldie, but goodie...Recommended.

Would be awesome...if it let you delete the "original" file if you choose to. The program only wants to delete the dup files. if you select the original file and try to delete it, it prompts for conformation, but then does nothing.

As for me Simple Duplicate Finder is the best dup cleaner so far.
In my perfect world all programs has classic UI and do only what they should )))

The author changed the name to Simple Duplicate Finder. Doesn't appear to have a new version. Says it its supported only in WinXP and Win7.

I've updated the Database to reflect a program rewrite, e.g. new name, icon, image, UI, weblinks, etc...

"Abnormal program termination"

That's what I got everytime I tried to run it on my dad's 500GB external HD.
