Simple Duplicate Finder v1.2.0.3

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.

For some reason, it shut down my computer, i dont know if it was an accident by me, but i ran the program, and walked off, came back a few minutes later and "windows is shutting down" screen was up. odd..

Nice simple program. Fast and easy. I would have liked to have seen file details beside each, but that's ok. I just needed it for a quick cleanup anyways.

Use duplicate finder, it helped me to find and remove duplicate files from my pc, it has great feature in which u can move or delete the selected files or folders. i found it on google search it says it can remove duplicates with great accurecy.

I haven't seen the results yet, it has been running since yesterday. The first time I ran it I accidentally hit the close dialog 'X' in the upper right hand corner. Damn. It would have been nice if the program had a "do you really?" question. It would also be nice to see a pause option or save and continue later option. This is only a 2/3rd's full 300G drive so I don't understand the 24 hour analysis time. You can't view the results as they are created you must wait until the entire results are in. Hope I live long enough.

I tried to get rid of this program in favor of more advanced duplicate finders but found I missed its simplicity and ease of use.

"Abnormal program termination"

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

the author has redesigned his hp, dismissed many apps, this one is now called Smart Duplicate Finder (

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


TP109 2012-10-07 00:30

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.

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 )))

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.

gregoryg72: I use DoubleKiller for this purpose:
