To delete duplicate files in Windows 11 using Windows Terminal:

  1. Open Start Menu and type: terminal (or powershell or cmd).
  2. Click Run as administrator on the right.

  4. Next, type: del followed by a wildcard expression that matches the name or extension of the file you want to delete. For example, del *-Copy.jpg will delete all JPG files with -Copy at the end of their names (indicating they are duplicates). You can also use ? (question mark) to match any single character or . (period) to match any file name or extension.
