You can access the entire directory tree using the code below

Kotlin

fun openDirectory(pickerInitialUri: Uri) {
    // Choose a directory using the system's file picker.
    val intent = Intent(Intent.ACTION_OPEN_DOCUMENT_TREE).apply {
        // Optionally, specify a URI for the directory that should be opened in
        // the system file picker when it loads.
        putExtra(DocumentsContract.EXTRA_INITIAL_URI, pickerInitialUri)
    }

    startActivityForResult(intent, your-request-code)
}

Java

public void openDirectory(Uri uriToLoad) {
    // Choose a directory using the system's file picker.
    Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);

    // Optionally, specify a URI for the directory that should be opened in
    // the system file picker when it loads.
    intent.putExtra(DocumentsContract.EXTRA_INITIAL_URI, uriToLoad);

    startActivityForResult(intent, your-request-code);
}
