The FT11 file format serves as a vector graphics template specifically designed for Macromedia FreeHand MX (version 11), a software application subsequently acquired by Adobe Systems. These templates facilitate the creation of consistent technical illustrations and graphic designs by storing reusable layouts, vector paths, and document settings. As a legacy format following the software's discontinuation in 2007, modern support is limited primarily to conversion tools and older versions of Adobe Illustrator.
