The file reader lets you open files like ODF (Open Document Format) documents created using LibreOffice or OpenOffice wherever you are. In the bus on your way to school wanting to look at your notes before the big exam? No problem! With the Document Reader you can open files wherever you like and read & search through your documents to go in a clean and simple way.
