Files blueprints in plugin not working

I’ve set a plugin up containing all my basic setup (snippets & blueprints) that I use for every site. This is all working apart the files templates - I’ve declared them in the plugin file, but Kirby isn’t seeing them. Is this expected or an issue? It works fine if i copy them under site/blueprints/files/.

I’ve set them up like this. Tabs and fields work fine, but its not seeing the files blueprints from the plugin.

'blueprints' => [
  // TABS
  'publishing'      => __DIR__ . '/blueprints/tabs/publishing.yml',
  'seo'             => __DIR__ . '/blueprints/tabs/seo.yml',
  'socialmedia'     => __DIR__ . '/blueprints/tabs/socialmedia.yml',
  'content'         => __DIR__ . '/blueprints/tabs/content.yml',
  'sitefiles'       => __DIR__ . '/blueprints/tabs/sitefiles.yml',
  // FIELDS
  'settings'        => __DIR__ . '/blueprints/fields/settings.yml',
  'logo'            => __DIR__ . '/blueprints/fields/logo.yml',
  'socialfallback'  => __DIR__ . '/blueprints/fields/socialfallback.yml',
  // FILES
  'audio'           => __DIR__ . '/blueprints/files/audio.yml',
  'docs'            => __DIR__ . '/blueprints/files/docs.yml',
  'imagebasic'      => __DIR__ . '/blueprints/files/imagebasic.yml',
  'imagefeature'    => __DIR__ . '/blueprints/files/imagefeature.yml',
  'imagefocus'      => __DIR__ . '/blueprints/files/imagefocus.yml',
],

You have to prefix them like the page blueprints:

'files/audio'           => __DIR__ . '/blueprints/files/audio.yml',

Ah ha! sorted… thanks.
