You can try below code for that

public void openFolder(){
     Uri selectedUri = Uri.parse(Environment.getExternalStorageDirectory() + "/myFolder/");
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(selectedUri, "*/*");

    if (intent.resolveActivityInfo(getPackageManager(), 0) != null)
    {
        startActivity(intent);
    }
    else
    {
        // if you reach this place, it means there is no any file 
       } 
}
