In this tutorial you learn how to use a command called robocopy to copy files in command prompt.
command used: robocopy “C:\Program files\internet explorer” “c:\explorer” /E /COPYALL /XJ /r:1 /w:1
another useful thing about Robocopy: When you copy the contents from one folder into another folder, it will automatically skip files that have already been copied previously (or are the same) instead of overwriting them, which save stime.
