Details
You must use the io.flush() or io.close() functions to write data to the file system.
Data is not automatically written to a file when you use the io.write() function. The io.write()
function buffers data; it may not be written to the USB drive immediately. Use the io.flush()
function to immediately write buffered data to the drive.
