@Jym77 I have been looking at this one.

I can see how to easily achieve this, but I am unsure how best to represent this on the site.

Where do we add a button or link to show the directory structure?

Thoughts welcome.

Not sure…
Maybe in the left menu?
Maybe we don't really need a link from the site, it's just that if I end up at https://act-rules.github.io/test-assets/moon-audio/moon-speech-transcript.txt (e.g. by copy/pasting a URL from within a test case) I can change the URL to go up and see the rest?

Going through the website, it may be best to put it here: https://act-rules.github.io/pages/implementations/testcases/

I will see what I can come up with. Ta.
