Editors' Review


This program tames directories by searching and deleting duplicate files, but its same-name search function could spell disaster for some users.

CloneMaster compares file names, sizes, and dates for user-selected drives and directories. Boasting a tabbed interface, the program returns a list of suspected duplicate files. You can manually choose files for deletion or allow the program to choose. Files with the exact same name, size, and date--but in different directories--are good candidates for deletion. However, files compared by name only and found in different directories are often necessary for various programs and deleting the duplicate could cause problems.

As a result, we found CloneMaster much safer with the duplicate-name function disabled. Unfortunately, the demo's delete feature is disabled, a serious limit to this app's usefulness. Still, CloneMaster performs its intended task well and is recommended for all users who maintain many directories of files. Digital photographers will find it especially useful.

"Nice interface, fast and accurate."

March 27, 2010  |  By friesenj

 |  Version: CloneMaster 5.0


Much faster then v4, very easy to use, find all my duplicates and can now print the expanded list of duplicates.


so far nothing to complaint.


In general I am very please with this software, it find accurate duplicates, it find the duplicates by comparing the file data itself and not using CRC or other methods that is not 100% accurate. just love the new interface.

"Nice UI, but reported false duplicates."

The user interface is nice, and it completes the scan fast.


Reports too many false duplicates (in fact I gave up searching through the false duplicates before I ever found an actual duplicate)


So much for 100% match.

The publisher claims that the software finds duplicates "by comparing the file data itself ensuring 100% accuracy." I can't say whether they are actually comparing the file data, but I can say that whatever they are doing was closer to 0% accurate for me...

In my job, I am constantly recieving large amounts of data from many customers. I try to keep things organized, but I'm not always sucessfull, and sometimes customers just add new files to the ones they sent me previously.

I need a utility that can scan a set of drives and/or folders and accurately identify 100% duplicates. Based on the claims made by the publisher, I was really excited to try CloneMaster v5.00.

My first test was on a set of folders where I was curious about whether I had duplicates. At first things looked very promising as the process was moving along rather quickly, but as it started to identify duplicates I became less ethusiastic. I waited until it finished and then reviewed the results. I spent about 10 minutes looking through each of the supposed duplicates, but none of them were actual duplicates. I even opened some of the text files that it reported as duplicates, and I could see numerous differences with my naked eye. I was disheartened and gave up on the remaineder of the results before I even found a true duplicate.

Thinking this was this just a fluke (or that I had been hungry during the previous test), I ran it again on another day . This time I used a set of folders that I know contains are large number of duplicates. Again it performed the comparison remarkably fast (especially since it was over 45GB of files). Unfortunatly this test ended in the same manner as the previous: I searched through the results, finding only "false posative", in the end I gave up on the remainder of the results before I actually found any true duplicates.

I will admint that I had a colleage tell me that he used a previous version of the utility and didn't have nearly the number of false posatives that I did.

Maybe there is something unique about the files I am scanning, maybe I was using the utility incorrectly, or maybe there is an issue with version 5.00. Either way this utility did not work for me.
