HTML not HTM file, how?

[tom powell]

I've tried using WebHelp and HTML5 as the output type, but our end user tells me they are .htm files. And they want .html.
Can I have Flare produce html?

use the Advanced tab in each target, select "Use custom file extension for topics" and input html in the text box

BTW, there is no difference between the actual files, other than the .htm and .html extension.

It will only actually matter on a server, if the server is (badly) set up to only handle html and not htm extensions.
