13.1.6 Links between published files
------------------------------------
To create a link from one Org file to another, you would use something
like ‘[[file:foo.org][The foo]]’ or simply ‘file:foo.org.’ (
Hyperlinks). When published, this link becomes a link to ‘foo.html’.
You can thus interlink the pages of your "org web" project and the links
will work as expected when you publish them to HTML. If you also
publish the Org source file and want to link to it, use an ‘http:’ link
instead of a ‘file:’ link, because ‘file:’ links are converted to link
to the corresponding ‘html’ file.
You may also link to related files, such as images. Provided you are
careful with relative file names, and provided you have also configured
Org to upload the related files, these links will work too. See
Complex example, for an example of this usage.
