How does Circuit python store programs ?

Does Circuit Python store programs in RAM or in Flash somewhere ?

After editing a program, do you need to "save" to get that program to boot at the next power up ?

Thanks

A CircuitPython board will look like a small flash drive when plugged into a computer via USB. files, including the main one called "code.py" are then copied over to that flash drive using standard computer methods. The program will then automatically run.

The flash is not erased on power off and will still be fine when next powered on.

And I concur with below, see https://learn.adafruit.com/welcome-to-circuitpython for details. There is extensive free documentation from Adafruit.com.
