Any files in the subfolder
files of the wiki folder will be available via the route
\files\<uri-encoded-filename>. For example: http://127.0.0.1:8080/files/Motovun%20Jack.jpg
This can be useful for publishing large files that you don't want to incorporate into the main wiki (PDFs, videos, large images, etc.).
Static files can be referenced directly:
[ext[./files/a-big-document.pdf]]- to make a link to a PDF
[img[./files/a-big-image.png]]- to embed an image
Alternatively, the _canonical_uri field can be used to reference the files as external tiddlers.
