This is a very simple trick, you don`t need any additional software just a card reader (or mass storage usb mode)
1. Change ``PRIVATE`` folder to be visible (uncheck hidden in attributes by right click on folder) with card reader or usb mode....
2. Open built in file manager
3. Use find option and insert ``Private`` (for card not phone)
4. Be patient and don`t interrupt the searching process..... and you should now see the private folder and be able to edit files in it and all subfolders....
