According to me in my opinion Duplicate Files Deleter is the best because I am still using it now for more than 3 years & will continue to do so as it is so user friendly, simple to use & you can do anything with it & I would definitely recommend it to everyone out there who wants to sort/manage/delete any of their duplicate files & you can choose to delete any files you don't want across all platforms just like myself who have been using this amazing software without any problems. Also it supports all file extensions out there. But please backup important files first. Please use it to believe me.
