The FT9 file format is a proprietary vector graphics document type generated by Macromedia FreeHand 9, a software application subsequently acquired by Adobe Systems. It stores scalable vector illustrations, multi-page layouts, and typography primarily utilized in professional graphic design and print publishing workflows. Since Adobe discontinued the FreeHand product line in 2007, this legacy format is now obsolete and requires specialized conversion tools for access in modern applications.
