If you are wondering how to find duplicate photos, I have the right answer for you. You see, I used to share my laptop with my sister, and we both tended to download photos, with many of them being duplicates. So, when my sister got her own computer, I decided to erase every unnecessary photo that was taking up space. However, I did not have time to search through every folder manually, so I found my solution on YouTube. There was this video on a program called Duplicate Finder which scans your system for duplicates and then erases them, leaving more free space and speeding up your computer.
