3) The last 6 log files must be stored. If the sixth file is already full (i.e. is 5 MB), then you need to delete the first file and create a new one. Where is this condition met?The requirement is the one above. I don't understand something, where do we change the condition to meet the new requirement "if the sixth file is already full you need to delete the first file and create a new one" . Is this something the program does automatically after we set MaxFileSize to 5MB
