In this section, we will focus on the manual way to compare files based on appearance, names, and extensions. Now, follow the steps below to eliminate similar files on Windows 11 or 10. 

  • Open the File Explorer on your Windows. Then, go to the location where you want to scan and remove the duplicate files. For Instance: This PC>Downloads.
