Learn how to open the Arduino15 folder on your system.

Windows

For a standard Arduino IDE installation the folder is found at C:\Users\{username}\AppData\Local\Arduino15.

1. Open your user folder in Explorer.

2. Look for a folder with the name 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.

   

   On Windows 7, the setting can be accessed from Explorer by clicking the Organize button, opening the View tab and selecting Show hidden, files, folders and drives in the Hidden files and folder section.

3. Open the Appdata folder.

4. Open Local.

5. Open Arduino15.

If you installed Arduino IDE from the Windows Store the folder is named ArduinoData, and is in a different location:

1. Open your user folder in Explorer.

2. Open your Documents folder.

3. Open the ArduinoData folder.

macOS

1. Open Finder.

2. In the menu, click Go.

3. Hold the option key. A Library row will appear in the menu. Click it.

4. Within the Library folder, open Arduino15.

Full path: /Users/{username}/Library/Arduino15

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. You may have to scroll down to see it since files with the . prefix may be listed after the others.

Note: By default the folder is hidden; therefore, if you’re unable to locate the Arduino15 folder please refer to the bottom of the page.
