The usbd_msc example uses the FatFS library to handle files (create, erase etc.) and It does not use the stlib.h

Yes you are right. I refer to the nRF USB next to the reset button not the debugger's. No I haven't seen the mass storage example. I will check it out. Thank you

Which "USB cable" are you referring to - there are two on the DK !

Have you looked at the USB MSC (Mass Storage) example:

Yes, your thought is absolutely correct . I just I thought that since I will be using the USB cable, I could use it to create a file with my data this way.

Why does it have to be a file on the nRF ?

Wouldn't it make more sense to just have the nRF send the data, then the phone - which is far better equipped for such things - can put it into a file, if required.
