nRF52840 SDK16 - USB MSC Example - What is happenning when the external flash memory get full?

Hi everyone,

I am using the nRF52840 DK and I am experimenting with the USB MSC example. My purpose is to record data from an IMU device and store them in files. Then to read the files and transmit the data over bluetooth to the central.

I have two questions

1. Is there any limitation regarding the file size?

2. What is happening when the memory is getting full?

Thanks in advance
