Scenario: I wanted to transfer few books to usb drive attached to my phone via usb otg.
I noticed:
1. Inability to select multiple books at a time to send to usb drive. (Only one book can be copied at a time)
2. I cannot use native file manager to do so. (I had to use es file explorer)
3. Books so sent have 36 letter id as file name and not the name of the book. (This we have discussed yesterday. Hope @chaley has fixed this and here onwards we can use book names as file names)
