The FT7 file format represents a vector graphics drawing created by Macromedia FreeHand 7, a now-discontinued illustration software subsequently acquired by Adobe Systems. These files primarily store scalable vector illustrations, page layouts, and graphic design elements used in professional print and digital publishing. As a legacy format, it is rarely encountered in modern workflows, though compatible viewers or converters such as Adobe Illustrator may still be required to access archived content.
