The software included here writes data in a file named PAXCOUNT.xx, where xx can range from 00 to 99. The software starts with 00, checks to see if such a file already exists and if yes it will continue with the next number (up to 99 - in this case it will return no sd-card). So an existing file will not be overwritten. The software included here writes data in a file named PAXCOUNT.xx, where xx can range from 00 to 99.

So an existing file will not be overwritten.
The data is written to the card and after 3 write-operations the data is flushed to the disk. So maybe the last 3 minutes of data get lost when you disconnect the PAXCOUNTER from power. The data is written to the card and after 3 write-operations the data is flushed to the disk. Thus, up to the last 3 records of data will get lost when the PAXCOUNTER looses power.
And finally: this is the data written to the disk: And finally: this is the data written to the disk:

Format of the data is CSV, timestamp is ISO8601, which can easily imported into LibreOffice, Excel, Influx, etc. Format of the data is CSV, timestamp is ISO8601, which can easily imported into LibreOffice, Excel, Influx, etc.
Voltage is logged, if the device has a battery voltage sensor (to be configure in board hal file).
