From the backoffice of your store click on the Pages icon or button. Near the bottom of the page will be a button that is either Advance Editing or Basic Editing. If it says Advance Editing click on it and it will put you into the Advanced editing mode. (if it says Basic editing you are already in Advanced editing mode.)
Now select the page you want to change the file name on from the list and click on the Edit Page Content button. Near the bottom of the screen is a field "File name:" where you enter the file name you want to have. Make sure it ends with a valid extension or the web server may not serve it up properly.
