I'm using the Cmore to datalog onto a USB flash drive. If the USB drive becomes full, I want to push the oldest log files out of the USB drive and write in the new ones. With the amount of data we 're logging there is room for months of data on the stick, and we only want to upload it every few months or when there is a failure. Sometimes the drive is full before we upload, and the newest data is not there because it was already full. I don't want to overwrite every day, as then if the new day's data is corrupted or there is a PLC or HMI failure then the old data (which would then be needed) would be overwritten on power-up. Is there a way to do this, without manually erasing the old files?

The EA9 panels with the latest firmware will overwrite the oldest file instead of just filling up.
