Arduino IDE (Arduino15 folder)

Development Tools IDE 2.x
1

Hello.

I want the 'Arduino15' folder to be on the D: drive, so I used ‘mklink’ to achieve this. Unfortunately, for some reason, the Arduino IDE isn't working properly – it always wants to load some libraries when it starts. When it's on the C: drive, everything works fine. What could be the problem?

Hi @PRLJacek. Which version of Arduino IDE are you using (e.g., "2.3.6")? The version is shown on the window title bar and also in the dialog that opens when you select Help > About (or Arduino IDE > About Arduino IDE for macOS users) from the Arduino IDE menus.

I ask for this information because I want to give you the appropriate instructions for the IDE version you are using.

Please provide a more detailed description of what you mean by this.

Are you drawing this conclusion from a message you see in Arduino IDE? If so, please provide the full and exact text of the message.

Arduino IDE stores various files in the "data folder".

The default location of the "data folder" is:

C:\Users\<username>\AppData\Local\Arduino15\

(Where <username> is your Windows username)

However, the location is configurable via a configuration file. The location of the configuration file is:

C:\Users\<username>\.arduinoIDE\arduino-cli.yaml

(where <username> is your Windows username)

The "data folder" location is configured via the directories.data key in that configuration file.

So my recommended solution is to do this:

  1. Select File > Quit from the Arduino IDE menus if it is running.
    All Arduino IDE windows will close.
  2. Remove the symbolic link/directory junction/whatever you created using mklink.
  3. Start any text editor application.
  4. Open the file at the following path on your hard drive:
    C:\Users\<username>\.arduinoIDE\arduino-cli.yaml
    (where <username> is your Windows username)
  5. Add the following lines to the bottom of the arduino-cli.yaml file:
    directories:
 data: <data folder path>
  6. Replace the <data folder path> placeholder with the full path of the location you want to use for the "data folder" (e.g., D:\Arduino15).
  7. Save the file.

Thank you very much for your help! It works fine now. :slight_smile: The problem is solved.

You are welcome. I'm glad it is working now.
