If you simply copy the Arduino IDE 2.x installation files to a USB drive and plug it into another computer, the IDE will launch, but it will attempt to read and write data to the host computer’s default local directories rather than your USB drive. The Solution: A Fully Portable Workflow for Windows
Some advanced scripts can use relative paths or environment variables to make configurations more portable across different drive letters.
@echo off SET "CDIR=%~dp0" :: Redirect the Arduino CLI and core files SET "ARDUINO_DATA_DIR=%CDIR%arduino-home" :: Redirect the IDE configuration files SET "ARDUINO_USER_CONFIG_DIR=%CDIR%user-data" :: Start the Arduino IDE using the redirected paths start "" "%CDIR%Arduino IDE.exe" --user-data-dir "%CDIR%user-data" Use code with caution. Step 3: Save and Test the Script In Notepad, click . Navigate to your main Arduino_IDE_Portable directory. Change "Save as type" to All Files ( . ) . Name the file Launch_Portable.bat and click Save . arduino ide 2 portable
The table below provides a clear technical comparison to help you decide which version suits your needs.
: Share an identical development environment with students or team members by copying a single folder. If you simply copy the Arduino IDE 2
Start by downloading the ZIP archive of Arduino IDE 2.x from the official Arduino website, not the installer version. Extract the archive directly onto your USB drive or into a folder you plan to move.
When launched in September 2022, it brought a sleek new interface, autocomplete, and a built-in debugger. However, users quickly discovered a major drawback: the portable folder no longer worked . Step 3: Save and Test the Script In Notepad, click
Installing ESP32, ESP8266, or specialized AVR cores will download files directly into your portable data folder.
By default, the IDE might still try to look at your computer's local "Documents" folder for your sketches. Let's lock that down to your portable folder. Launch the IDE using your new Launch_Portable.bat file. Go to (or press Ctrl + , ).
To successfully build a portable environment for Arduino IDE 2.x, make sure you have:
