The nRF chip has no access to that.

If i try with USB CDC-acm example is this  possible to read file from Jlink drive. or else only option is to use as USB mass storage

You've flagged this as nRF52810.

The nRF52810 has no USB peripheral.

If you want a USB connection from the PC to the nRF chip, then you will need an nRF52840.

ya yes.. I am using nrf52840 as central.

If i use CDC acm example ,it is necessary to use fatfs for file operations?

[awneil]

If you want to do file operations, you will need some sort of filesystem!

But CDC ACM is nothing to do with files.
