Flexy Historical data clean up

I understand that as the memory gets filled up due to us collecting historical data @ 60s intervals for 8 real values the logs will start to write over the older data. I would like to transfer the data files out once a month. Is there a way to delete the existing files after that?? Then the system would start logging again and create the files over again??

Thanks in Advance


Yes, there is an example of how to do that here: SD FIFO files management
