Where can I find the Arduino15 folder?

  • Updated

The Arduino 15 folder is where the IDE stores its data, from your IDE preferences, to the cores for the boards you have installed.

This folder is available in the following paths:

  • On Windows
    • Standard IDE: C:\Users\{username}\AppData\Local\Arduino15
    • Windows app: C:\Users\{username}\Documents\ArduinoData\packages
  • macOS: /Users/{username}/Library/Arduino15
  • Linux: ~/.arduino15

By default, this folder is hidden. If you can't find it, use this procedure:

  • Windows: In Start > File explorer > View > Show/hide > Advanced settings, check Hidden items.
  • macOS: Open Finder and navigate to the home folder (/Users/{username}). From the Finder menu bar, click on View > Show View Options, and tick Show Library Folder. The Arduino15 folder can now be found in {username}/Library.
