Hi @abtj_90
On the first run after a fresh installation Arduino IDE automatically installs a collection of fundamental libraries (known as "built-in libraries").
The list of libraries that are installed is defined here:
https://github.com/arduino-libraries/Arduino_BuiltIn/blob/main/library.properties#L10
depends=Ethernet,Firmata,Keyboard,LiquidCrystal,Mouse,SD,Servo,Stepper,TFT
It also installs the "Arduino_BuiltIn" library. However, that library is not of interest to the user. It's sole purpose is to act as a container for the metadata I linked above.
Arduino IDE 2.x also automatically installs the "Arduino AVR Boards" platform on the first run after a fresh installation. This includes the installation of the libraries you see here:
It is important to understand that these "platform bundled libraries" are only accessible when you are compiling with a board of that platform selected from the Tools > Board menu in Arduino IDE. So you should not think of these libraries in the same way as the "built-in libraries", which are always accessible.
It is easy to miss this distinction because, by convention, all boards platforms include their own bundled copies of at least the SPI and Wire libraries. Even though you are using a different library from one board to another, those libraries have a compatible API so that fact is not noticeable to the user. This is a common source of confusion for users who expect there to always be an EEPROM and SoftwareSerial library, even though most boards platforms don't have those libraries. You can see our AI buddy inherited the same confusion and has mixed "built-in" and "platform bundled" libraries together in the same list.
This is only true when using Arduino IDE 1.x. The Arduino IDE 2.x installation does not include any libraries. Since the libraries are installed on the first run, the difference is not noticeable to the user, but Arduino IDE 2.x installs the libraries to a different location (it is not really feasible for an application to write to the application folder due to restrictions imposed by the OS for security or by the packaging system).
