Freeware to Find and Remove Duplicate Files in Windows

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 files finder for Windows

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

DoubleKiller

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.

dupeGuru

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

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.

Auslogics Duplicate File Finder

This freeware from the stables of Auslogics will help you to find and remove useless duplicate files, stored on your Windows PC.

Features:

  • Finds identical pictures, documents and any other files
  • Compares files not only by names, but by their content
  • Can significantly increase free space on your disk
  • Helps you to organize your media collections
  • Reduces time needed to defragment your hard drive

NoClone

NoClone is another free software which uses real-time byte-to-byte comparison to detect duplicate files regardless of their file names. You can limit the search to specific file types (images, programs etc.) as well as by size, date and location.

The free edition of NoClone restricts itself to 300,000 files in a single session.

Other similar freeware in this category are, CloneSpy and DupScout. If you need to find duplicate images, try Awesome Duplicate Photo Finder.
