The correct location for the user’s libraries is the libraries subfolder of the sketchbook folder. The sketchbook folder location is set in the Arduino IDE at File > Preferences > Sketchbook location. The Arduino IDE installation also contains a libraries folder, which is for the bundled libraries.

Where is the Arduino library folder?

Please note: Arduino libraries are managed in three different places: inside the IDE installation folder, inside the core folder and in the libraries folder inside your sketchbook. The way libraries are chosen during compilation is designed to allow the update of libraries present in the distribution.

Where is the Arduino IDE installed?

Arduino will automatically be installed in “C:Program Files (x86)Arduino”. If you want to change the folder, click “Browse” and select the desired folder. Click install to start the installation.
