Data file formats

This article is a stub. You can help the OLPC project by expanding it.

Introduction

Because the OLPC has limited storage and limited RAM, it is not a good idea to support every data format used on regular PCs. It makes more sense to use our PCs to convert data than to put that burden on the OLPC.
