[batch-file] Batch file to copy files from one folder to another folder

My favorite one to backup data is:

ROBOCOPY "C:\folder" "C:\new_folder" /mir

/mir is for mirror. You can also use /mov to move files. It reproduce the exact same folder. It can delete/overwrite files as needed. Works great for me. It's way faster than xcopy / copy. It's built in Windows as well.
