How to create a new folder using react-native -fs

Question

How can I create a folder at the root of the internal storage in a React Native application, ensuring that the folder and its contents persist even if the app is uninstalled? I've explored the directory paths provided by react-native-fs, but none seem to fully meet my requirements. Ideally, I'd like to create a dedicated folder at the root level of the internal storage and save my files within it. Could anyone guide me on how to achieve this effectively?

Google Play Console policies restrict access to the root of internal storage, and apps are encouraged to use other storage solutions like the app-specific directory provided by getFilesDir() method.

If you want to create a directory in the internal storage that persists across app installs and uninstalls, you can only use the app-specific directories provided by the Android system. Here's how you can do it in React Native:

import { Platform } from 'react-native';
import RNFS from 'react-native-fs';

const folderName = 'myPersistedFolder';

async function createPersistedFolder() {
  try {
    const filesDir = Platform.OS === 'android' ? RNFS. DownloadDirectoryPath : RNFS.DocumentDirectoryPath;
    const folderPath = `${filesDir}/${folderName}`;

    const folderExists = await RNFS.exists(folderPath);
    if (!folderExists) {
      RNFS.mkdir(folderPath)
            .then(() => {
              console.log('Folder created successfully');
            })
            .catch(error => {
              console.error('Error creating folder:', error);
            });
      console.log('Persisted folder created:', folderPath);
    } else {
      console.log('Persisted folder already exists:', folderPath);
    }
  } catch (error) {
    console.error('Error creating persisted folder:', error);
  }
}

createPersistedFolder();
