Describe the request

https://arduino.github.io/arduino-cli/1.1/platform-specification/ describes the platform specification. https://arduino.github.io/arduino-cli/1.1/platform-specification/#hardware-folders-structure describes its folder structure.

This folder structure does not correlate with what is seen when installing a specific platform via the board manager on Windows 11 in the Arduino IDE.

I wish for the documentation to be updated to be correct for how it looks in a installation on Windows

Describe the current behavior

I asked Perplexity why I saw this difference between my installation and what the platform specification said, and got a pretty sold answer I believe.

My question

The Arduino platform specification says the directories look like:

hardware/arduino/avr/...     - Arduino - AVR Boards
hardware/arduino/sam/...     - Arduino - SAM (32bit ARM) Boards
hardware/yyyyy/avr/...       - Yyy - AVR
hardware/xxxxx/avr/...       - Xxx - AVR

But when I check in explorer in Windows 11, it looks like:

packages\arduino\hardware\avr\1.8.6\cores\arduino

I don't understand why.

The answer

Arduino CLI version

1.1.0

Operating system

Windows

Operating system version

11

Additional context

The entire nomenclature around Arduino "platform" and "core" is confusing. There are numerous Stack Overflow, forum and what not questions out there about this. For example even this repo has this issue #549.

Seeing this folder structure difference completely adds to this confusion.
