When you delete a frame (frames: The named subwindow of a frames page. The frame appears in a Web browser as one of a number of window regions in which pages can be displayed. The frame can be scrollable and resizable, and it can have a border.) from a frames page (frames page: A Web page that divides a Web browser window into different scrollable areas that can independently display several Web pages. One window can remain unchanged, while the other windows change based on hyperlinks that the user selects.), the frame contents are kept in the Web page file.
Note The last frame of the frames page cannot be removed.
