    "Fast and Accurate Duplicate File Finder"

    January 24, 2015  |   By billu.1840

    Version: Duplicate File Finder 5.5


    I have used Duplicate File Finder to eliminate thousands of duplicate images on my hard drive. It is easy to use and very fast. I tested the program by making small changes in identical files and found no errors. A great program and response to questions by the author was quick and concise. I would recommend this program to anyone looking for duplicate file finders.


    did not notice any cons

    "Byte-by-Byte comparison does not work"

    January 23, 2015  |   By Bill.Jones69

    Version: Duplicate File Finder 5.5


    Fast Byte-by-Byte comparison. Maybe useful for jpg files.


    Byte-by-byte comparison shows distinctly different files as identical. It doesn't show mp4 and mov files so you have to actually go to the directory to see if the files are identical. Byte-by-byte comparison seems to show files with same extension and size as being identical even though they aren't. For example, mov file of girls on surf board were considered identical to same size mov file of fireworks. Also, if you compare folder A to folder B it will automatically mark some folder A files for deletion and some folder B. You will have to manually correct this.


    Byte-by-byte comparison cannot be trusted. Given that, I doubt any of the comparisons can be trusted.
