-Then when you call `obj.create_derivatives` two new datastreams, 'thumbnail' and 'content_medium', will have been created with downsized images in them.
+Then when you call `obj.create_derivatives` two new files, 'thumbnail' and 'content_medium', will have been created with downsized images in them.
 
 We recommend you run `obj.create_derivatives` in a background worker, because some derivative creation (especially videos) can take a long time.
