Hello Mohammad!
To transfer data, for instance a style from the keyboard to USB stick, do as follows:
1. Find the style you want to transfer, press on it so it is highlighted.
2. Press File at the top of the screen.
3. You will now get a menu. Choose Copy.
4. At the top right corner of the screen you will now see Cancel, Select All, Copy. Choose Copy.
5. At the left side of the screen you will now see User, USB 1 etc.
Press the USB1 if you want the style on your USB stick.
6. Now press Copy Here at the right upper corner of the screen.
Hope this helps
All the best from Toril S
