18.6.2 Specifying a file extension for interfile links
To specify which file extension to use in links to other HTML files:
; FileSuffix = suffix used in xrefs for HTML: htm (default), html
Whether to set FileSuffix=html depends on the convention used on your site. Use htm (the default) unless you have a good reason to specify the full original html extension.
