tiptoi pen: Adding files manually
The tiptoi pen is a wonderful toy for small children. For new books one needs to copy audio files to the pen. There is a docking station for newer models that takes care of this, a synchronization app for Windows, but on linux one needs to download and copy them manually.
The files can be found on this webpage (just search for the book title).
Copy them next to the already present files on the stick, e.g. cp new_book_file.gme /mnt/tiptoi_device/tiptoi/.
