The Interchange File Format Animation (ANIM) is a raster animation standard developed by Electronic Arts for the Commodore Amiga personal computer. It was primarily utilized for storing digital video sequences and short animations through delta compression to optimize performance on early hardware. Although this legacy format is now obsolete, it remains essential for retro-computing enthusiasts and digital archivists dedicated to preserving historical computer graphics and software from the late twentieth century.

How to validate .anim files in Python
Python

with open(file_path, "rb") as f:
return f.read(8) == signatureHow to validate .anim files in Node.js
Node.js
