Most of us don’t give a damn about duplicate files present in our hard drivers but the truth is that they could eat a lot of disk space. Extra copies of existing files are always created by the operating system as well as application programs even though the user is unaware of it. You computer could really get cluttered with junk if this process continues for some time. Most of the time, extra copies of the files can be safely deleted. But how do you detect them? This is where the ‘Fast Duplicate File Finder’ comes in. It’s a free software that is designed with one goal in mind – find extra copies.

The app is actually pretty easy to use. All you have to do is to launch the program, start a new project and add a folder (or an entire drive) to be scanned. In a few seconds a complete list of duplicate files found on the target location will be displayed. You can delete unnecessary files right from this view itself. The program itself is pretty lightweight and is only around 1.6MB in file size. It does not add any startup entries or services to the system and will not consume half your computer’s resources.
