Free Duplicate File Finder software for Windows 10/8/7

Duplicate files are a problem, as you do not know which one contains the most current content. In case of collaborating, you may miss out on changes your co-worker did to the document if you open the wrong one. The worst case scenario may be that you and your colleagues do not know about duplicates and you all work on different versions of the file.

Though there are junk cleaners such as the Comodo System Cleaner and CCleaner, they fail to recognize and fix the problem of duplicate files. Hence you need dedicated software that can search and remove and merge duplicate file.

Free Duplicate File Finder software for Windows

This article talks about three such free software which will help you find and delete or remove duplicate files in Windows 10/8/7.


As evident by the name, DoubleKiller finds and removes duplicate files from your computer. The software from Big Bang Enterprises is available in two editions. One is free to use and you have to pay for the other edition. Of course, the paid edition does more work but you can get good results with the help of freeware too.

The software uses methods including hash comparison to compare files. The software is easy to use and hence I placed it at the first position.


Known popularly as the dupeGuru Music Edition, the latest version of dupeGuru adds music files comparison to the feature set.

In addition to removing duplicate files with similar filenames, it also has the capability to search within files – especially MP3s – to know if they are similar even in case the filenames are different. It presents you with the search results allowing you to select which one to keep and which one to discard.


WinMerge is a cross platform software that is works cross platform. The same software can be used on both Windows and Linux. You need not install the software so you can launch it directly from your pen drive – if you wish so. The search and merge feature helps you retain the mix of all the duplicate files having almost similar content. The GUI of WinMerge is good and makes it easy to locate similarities among different files. WinMerge will display visual differences & merge files & folders in Windows.
