SD Card Data Structure

2. The first datalogging session will then create a file TMC01001.XLS. All data will be saved to
this file until the number of columns reaches 30,000.
3. After 30, 000 columns a new file, TMC01002.XLS is created. This is repeated every 30,000
columns until TMC01099.XLS. At this point a new folder, TMC02 is created and the process is
repeated. TMC10 is the final folder.
