Download datasets

{{#Subtitle| This page deals with downloading Lingualibre.org's medias, both by hand and programatically, as packaged zip archives with rich filenames. When done, we have tutorials on how to clean up the resulting folders and how to rename these media files into web-friendly names such as {language}-word.ogg. Be aware of Lingualibre's data's size could be in 100s GB if you download it all. }}
