The FT8 file format is a vector graphics template developed by Macromedia for use with FreeHand 8, an application later acquired and discontinued by Adobe Systems. It serves as a preconfigured blueprint for creating standardized vector illustrations and page layouts without altering the original design structure. Since FreeHand development officially ceased in 2007, this legacy format generally requires specialized conversion utilities or older software environments for viewing and editing.
