4. Power up the Pico by plugging in the USB cable attached to
your computer.

appear in your file manager, as a USB Mass Storage Device
called RPI-RP2. (It may take a few moments for it to register.) If you
examine it with some drive manager software, you’ll see that the
Pico pretends to be a 128MB FAT flashdrive.
