Using CommonsDownloadTool

To download all datasets as zips :

• Download on your large device the scripts :
  • create_datasets.sh
  • CommonsDownloadTool/commons_download_tool.py
• Read them a bit, move them where they fit the best on you computer so they require the minimum of editing
• Edit as needed so the paths are correct, make it work.
• Run create_datasets.sh successfully
• Check if the number of files in the downloaded zips matches the number of files in Commons:Category:Lingua Libre pronunciation

Javascript and/or API queries

There are also ways to use a category name as input, then to do API queries in order to get the list of files, download them. For a start point on API queries, see this pen, which gives some example of API queries.
