The BLEND format is the native project container for Blender, an open-source 3D creation suite maintained by the Blender Foundation. It serves as a database for 3D assets, storing geometry, textures, animation data, lighting setups, and workspace configurations for rendering and modeling workflows. As a binary representation of the application’s memory state, the format is stable but requires caution regarding embedded Python scripts, which can execute upon opening if not sandboxed.

How to validate .blend files in Python
Python

"""Check if file is a valid BLEND by magic bytes."""

with open(file_path, "rb") as f:
return f.read(7) == signatureHow to validate .blend files in Node.js
Node.js

return buffer.subarray(0, 7).equals(signature);
}
Go
func IsBLEND(data []byte) bool {
