Duplicate File Finder, as the name of the application suggests it is a free tool which you can use in order to find and delete duplicate files present on your Windows system.

Duplicate Finder default window

What we are testing here is the free edition of Duplicate File Finder, which doesn’t have all the functions that the paid version has. For example all the tabs that can be seen on the image above next to the tab Locations, can’t be used in the free edition, which means that in order to enjoy things like advanced filters, file and folder exclusions you’re gonna have upgrade. Even without these options Duplicate File Finder can be very useful, mainly because it has very good duplicate file search engine, which is gonna search for:

  • Files based on their size and signature – the byte by byte search
  • Duplicate files based on name, extensions, dates and more
  • Music duplicates which are very common
  • Even something called non-duplicate unique files

Not checking if you have duplicate files could cause a lot of problems, in the end, if you’re not informed enough, it could even cost you money, not to mention that you’ll have problems with Windows running properly.
