Change the output of the output files
To change the file extension of your HTML output, use these simple steps:
Open the Style Designer (View > Style Designer).
- In the Page Styles section, select (or create, if necessary) the Default page style (or any other style for which you'd like to change the extension).
- On the Options tab, change the "Output file extension" setting from .html to your desired extension.
If applicable, you can also change the filename/extension of the TOC file from within the Format Settings (Format > Format Settings...).
- Regenerate your outout to apply the changes.
