2. Type the following command in Windows Terminal. Replace the folder paths with the actual locations of the two folders you wish to compare on your computer.

robocopy /L /NJH /NJS /NP /NS “path to first folder” “path to second folder”

Consider the following scenario:

robocopy /L /NJH /NJS /NP /NS “C:folder” “C:folder 2”

Tip: If your folder structure is intricate and manually entering the folder paths in the terminal is cumbersome, right-click the folder and choose Copy as path to copy the whole path to the folder. By right-clicking in the terminal window, you may paste the folder path into Windows Terminal.
