The file number returned from the

function to flush
Details
The file.write() function may buffer data instead of writing immediately to the USB flash drive.
Use file.flush() to flush this data. Data may be lost if the file is not closed or flushed before a
script ends.
If there is going to be a time delay before more data is written to a file, flush the file to prevent loss of
data because of an aborted test.
