How to use FileManager with MIT App Inventor and Kodular
An advanced file manager extension for Kodular.
Install extensions carefully
Use extensions from trusted developers, keep a backup of your project, and review requested permissions before importing an AIX file into MIT App Inventor, Kodular, or a compatible builder.
Import FileManager into MIT App Inventor
Use these general steps to import FileManager into an MIT App Inventor project. The exact screens can vary slightly as MIT App Inventor updates its interface.
- 1
Open your MIT App Inventor project, or create a new project before importing FileManager.
- 2
In the Designer, go to Palette → Extension → Import extension.
- 3
Choose or upload the .aix file. If your App Inventor environment supports importing by URL, you can use the creator-provided URL instead.
- 4
After import, drag FileManager from the imported Extensions area into the Viewer. Many extensions appear as non-visible components below the screen.
- 5
Switch to the Blocks editor and use the extension blocks shown for the imported component.
- 6
If the companion app does not immediately detect the new extension, restart the companion session or rebuild the APK/AAB before testing again.
Import FileManager into Kodular
Kodular also supports AIX extensions. Because Kodular's UI can change, treat these as practical generic steps and follow any creator-specific notes on the listing.
- 1
Open your Kodular project and keep a backup before adding FileManager.
- 2
Use Kodular’s current Assets, Extensions, or Palette extension import flow to import the .aix file.
- 3
Drag FileManager into the current screen after the extension appears in your project.
- 4
Configure any visible properties or non-visible component settings required by the creator documentation.
- 5
Open the Blocks editor, connect the extension blocks to your app logic, then test with the companion or a build.
- 6
If Kodular’s interface changes, follow the closest available extension import flow and the creator’s latest instructions.
