I missed the window for auto-migration of WLS into WordPress.
Fortunately my content was not lost, Microsoft had a limited time where you could obtain your old content in a ZIP file (SPACE.ZIP). This ZIP contains a bunch of HTML files which won't directly import into WordPress that I can see.
Can you advise me on a method to import this content into my blog where it will maintain post dates, comments etc?
If third-party utilities are necessary that's fine.
The blog I need help with is benryanau.wordpress.com.
