When it is used
Point a link at a token and mark it download, or use a token as the source of a non-image asset, and nanoesis infers a file field.
It is inferred from the markup. The file is published alongside the page and the link resolves to it.
Example
A download link with a token becomes a file picker:
<a href="{brochure}" download>Download the brochure</a>In the editor
In the editor this is a file picker: upload a document and the link points to it once published.
Use it for PDFs, spreadsheets, archives and anything that is not an image.
