    Dark Mode only. Difficult to see. Other reviews lead me to believe it is questionable software. I doubt this is better than CloneSpy.

    Czkawka 4.0.0 can be much more precise.

    Czkawka, although it has a terrible name for remembering it, has the BEST performance of all the software in comparison, and it's FOSS.
