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.

Validation Code

How to validate .ft9 files in Python

Python
def is_ft9(file_path: str) -> bool:
    """Check if file is a valid FT9 by magic bytes."""
    signature = bytes([0x41, 0x47, 0x44, 0x32])
    with open(file_path, "rb") as f:
        return f.read(4) == signature

How to validate .ft9 files in Node.js

Node.js
function isFT9(buffer: Buffer): boolean {
  const signature = Buffer.from([0x41, 0x47, 0x44, 0x32]);
  return buffer.subarray(0, 4).equals(signature);
}

How to validate .ft9 files in Go

Go
func IsFT9(data []byte) bool {
    signature := []byte{0x41, 0x47, 0x44, 0x32}
    if len(data) < 4 {
        return false
    }
    return bytes.Equal(data[:4], signature)
