How to validate .icb files in Python
def is_icb(file_path: str) -> bool:
"""Check if file is a valid ICB by magic bytes."""
signature = bytes([0x01, 0x01, 0x00, 0x00])
with open(file_path, "rb") as f:
return f.read(4) == signature
How to validate .icb files in Node.js
function isICB(buffer: Buffer): boolean {
const signature = Buffer.from([0x01, 0x01, 0x00, 0x00]);
return buffer.subarray(0, 4).equals(signature);
}

Frequently Asked Questions
What is a .icb file?
A .icb file is a ICB file.
What are the magic bytes for .icb files?
The magic bytes for ICB files are 01 01 00 00 at byte offset 1. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .icb file?
To validate a .icb file, read the first bytes of the file and compare them against the known magic bytes (01 01 00 00) at offset 1. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .icb files?
The primary MIME type for .icb files is image/x-tga.
Is it safe to open .icb files?
ICB (.icb) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
