Privacy policy. The WriteAllBytes method writes data to a binary file. If the append parameter is True , it will append the data to the file; otherwise data in the file is overwritten. If the specified path excluding the file name is not valid, a DirectoryNotFoundException exception will be thrown. If the path is valid but the file does not exist, the file will be created.
