Sharepoint Designer not opening HTML files

Question

I have a FBA website and then I extended it (to use Windows Authentication) to be able to access it with Sharepoint Designer. It is MOSS 2007 BTW.

When I open the extended site with the designer, it shows the MOSS website hierarchy but doubleclicking a aspx or .master files it does nothing.

I can open it in notepad... but not in the Sharepoint Designer.

Any suggestion on what may be wrong with this website/ designer?

Thanks!

Answer 1

Is this a trial version of the SharePoint Designer? It has happened that the trial version might not open the pages for you as explained here.

Otherwise, right-click on the page you wish to open and see/pick your option accordingly.
