Blot turns a folder into a website. Files in the folder become posts on your website.
Files and folders whose name starts with an underscore do not become posts or pages. You can link to or embed them in posts.
The files in your site’s folder are public. This is useful if you want to embed an image, a video or an audio file in a post. You can also use this to share files with your readers. For example, given the folder below, your readers can download Archive.zip if they visit /Files/Archive.zip on your site.
