How to validate .flt files in Python

Python
def is_flt(file_path: str) -> bool:
    """Check if file is a valid FLT by magic bytes."""
    signature = bytes([0x00, 0x01, 0x01])
    with open(file_path, "rb") as f:
        return f.read(3) == signature

How to validate .flt files in Node.js

Node.js
function isFLT(buffer: Buffer): boolean {
  const signature = Buffer.from([0x00, 0x01, 0x01]);
  return buffer.subarray(0, 3).equals(signature);
}

How to validate .flt files in Go

Go
func IsFLT(data []byte) bool {
    signature := []byte{0x00, 0x01, 0x01}
    if len(data) < 3 {
        return false
    }
    return bytes.Equal(data[:3], signature)
}
