Is there a usable file system?

Unfortunately I can't find anything about a file system to the Arduino RP2040 Connect. There is something called "littlefs" deep in the mbed folder. How can you use that?

Possibly

# Arduino Pico LittleFS Filesystem Uploader

Arduino plugin which packs sketch data folder into LittleFS filesystem image,
and uploads the image to Raspberry Pi Pico RP2040 flash memory.
<br>

## Installation
- Make sure you use one of the supported versions of Arduino IDE and have the Arduino-Pico core (https://github.com/earlephilhower/arduino-pico) installed.
- Download the tool archive from (https://github.com/earlephilhower/arduino-pico-littlefs-plugin/releases).
- In your Arduino sketchbook directory, create tools directory if it doesn't exist yet.
- Unpack the tool into tools directory (the path will look like `<home_dir>/Arduino/tools/PicoLittleFS/tool/picolittlefs.jar)`.
- Restart Arduino IDE.

On the OS X create the tools directory in `~/Documents/Arduino/` and unpack the files there.

## Usage
- Open a sketch (or create a new one and save it).
- Go to sketch directory (choose Sketch > Show Sketch Folder).
- Create a directory named `data` and any files you want in the file system there.
- Make sure you have selected a board and port.

Hi @RudolfAtRTC

Hope it's not too late.

You can find the example how to use LittleFS with ArduinoCore-mbed inside WiFiManager_NINA_Lite_RP2040.h of my WiFiManager_NINA_Lite Library and DoubleResetDetector_Generic.h

If you'd like, I can write and post a simple example to demo how to use LittleFS in ArduinoCore-mbed

What media is it for?

A built-in SPI flash
An external block device (one of SPI flash, DataFlash or an SD card).
Simulated on a heap block device on boards with enough RAM.
