The directories.user path is particularly important as it defines your "sketchbook" folder—where your sketches and user-installed libraries are stored. The directories.data path controls where board platforms and built-in libraries reside.
As of late 2025, Arduino IDE 2.x does not officially support "Portable Mode" by simply adding a
Open a terminal, navigate to the folder, and make the script executable by running: chmod +x launch_portable.sh Step 4: Run and Verify Your Setup
In older versions, you could create a fully self-contained environment on a USB drive with these steps: Download the (not the installer) from the Arduino software page Extract the ZIP to your USB drive. Create a new folder named inside the main extracted folder.
Rename the file to arduino-ide.AppImage to keep your commands clean. arduino ide 2 portable
This bypasses the system's global AppData directories, forcing the configuration states, themes, and window sizes to save exclusively to the specified folder on your drive. Managing Libraries and Board Cores in Portable Mode
It's worth noting that some users have reported mixed results with this method. The official Arduino documentation for portable installations still primarily references IDE 1.x, and the IDE 2.x implementation of this feature is less documented and potentially less stable.
The Arduino developers have noted that IDE 2.x is a major rewrite based on the Theia framework and Electron . Adding a native portable mode is currently a on their GitHub roadmap because most users now use personal laptops rather than shared machines, reducing the immediate demand for the feature. Arduino IDE 2.0 Portable
Running a portable IDE from a cheap USB 2.0 flash drive will result in slow compilation times. For the best performance, run it from a local solid-state partition or use a fast USB 3.0/3.1 external drive. If you want to fine-tune your setup, tell me: The directories
Right-click launch.bat and select "Edit" (using Notepad or any code editor). Paste the following command:
Ensure the "Save as type" dropdown in Notepad is set to .

folder by default, you must manually move these to your portable drive. Arduino Forum Extract and Run: arduino-ide.exe once from your portable folder to generate initial files. Move Data: Locate the folder (usually at C:\Users\%username%\AppData\Local\Arduino15 this folder and it inside your portable Arduino IDE directory. Edit Configuration: Find the configuration file arduino-cli.yaml (typically in C:\Users\%username%\.arduinoIDE Create a new folder named inside the main extracted folder
When you install packages via the Library Manager, they save directly into ArduinoIDE_Portable\sketchbook\libraries .
Extract the contents of the downloaded ZIP archive directly into this folder.
