Learn how to uninstall Arduino IDE.

Uninstalling the application

• Windows:
  • In Windows 10: Open the start menu and find the Arduino application. Right-click on it and select Uninstall.
  • Alternatively, open Explorer and run C:\Program Files\Arduino IDE\Uninstall Arduino IDE.exe. Or if you’re using Arduino IDE 1.x, C:\Program Files (x86)\Arduino\uninstall.exe.
• macOS:
  1. Open Finder.
  2. Go to the Applications folder.
  3. Remove the Arduino.app or Arduino IDE.app application.
• Linux: The application files are located wherever they were extracted in the installation process. If you need help finding it you can follow these steps.

Removing additional files

Arduino IDE saves your sketches, library files and board cores outside the application folder. This way, they will still be available if you’re updating Arduino IDE to a different version, or if you reinstall it later. Optionally, you can also remove these files:

The Sketchbook contains your saved sketches and installed libraries. It is located in your Documents folder by default, inside the Arduino subfolder.

• Windows: C:\Users\{username}\Documents\Arduino
• macOS: /Users/{username}/Documents/Arduino
• Linux: /home/{username}/Arduino

The Arduino15 folder. Located in these locations by default:

• Windows: C:\Users\{username}\AppData\Local\Arduino15. Open your Users folder in Explorer and look for a folder called AppData.
  • This folder is hidden by default. In newer versions of Windows, you can display hidden items by clicking the View tab, and checking Hidden items.
• macOS: /Users/{username}/Library/Arduino15 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.
• Linux: The folder is located in home/{username}/.arduino15 and is hidden by default. To show it, click the hamburger button and check Show Hidden Files.
