Anyone know of a trustworthy, easy to use (ideally FOSS) program that will allow me to easily identify and compare duplicate files on windows 10? Alternatively, could you point me in the direction of a more appropriate magazine to ask in?

As title suggests, I'm looking to clean up my desktop from any duplicates I have across my different drives, but would also like to be able to easily compare them to make sure they definitely are the same before I delete them....
