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" (
On the other hand AllSync, from the same company, is time-limited shareware--perhaps Lee got the two confused?

@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
