I am confused by this screen shot. The headline says circuitpython and nrf52840. But your windows folder says micropython. Thats different from circuitpython. And it says esp32s3, not nrf52840. Ok. You…

You must be having the CircuitPython binary right! From your message what I understood is that you need help loading it to the board.
Can you explain what exactly you are trying to do?
If you are an absolute beginner then follow the instructions given the link:

you can program it by

nrfjprog -f NRF52 --program pca10056_bootloader-0.8.3_s140_6.1.1.hex --verify --reset

make sure you have installed nrfjprog installed

Nope it's not the bootloader. It's a uf2 image of circuitpython. You need uf2-bootloader in-order to run that application

The flow is as follows

resetHandler -> UF2_Bootloader -> Circuit Python image (*.uf2)

I am not a windows user! Dont know how to help you with that. But I would strongly recommend you to do the following things

1) Unistall the nRF Command Line Tools
2) Check which version of windows OS you are using (32/64)
3) Download the nRF Command Line Tools by checking the correct OS version
4) Install the nRF Command Line Tools
