    Note that overflow is not detected, and the return value may be negative if overflow occurs. See sizeOfAsBigInteger(Path) for an alternative method that does not overflow.
    
    Parameters:
    
    path - the regular file or directory to return the size of, must not be null.
    
    Returns:
    
    the length of the file, or recursive size of the directory, in bytes.
