Validation Code

How to validate .list files in Python

Python 
def is_list(file_path: str) -> bool:
    """Check if file is a valid LIST by magic bytes."""
    signature = bytes([0x54, 0x68, 0x69, 0x73, 0x20, 0x69, 0x73, 0x20, 0x54, 0x65, 0x58, 0x2C])
    with open(file_path, "rb") as f:
        return f.read(12) == signature

How to validate .list files in Node.js

Node.js 
function isLIST(buffer: Buffer): boolean {
  const signature = Buffer.from([0x54, 0x68, 0x69, 0x73, 0x20, 0x69, 0x73, 0x20, 0x54, 0x65, 0x58, 0x2C]);
  return buffer.subarray(0, 12).equals(signature);
}

How to validate .list files in Go

Go 
func IsLIST(data []byte) bool {
    signature := []byte{0x54, 0x68, 0x69, 0x73, 0x20, 0x69, 0x73, 0x20, 0x54, 0x65, 0x58, 0x2C}
    if len(data) < 12 {
        return false
    }
    return bytes.Equal(data[:12], signature)
}

Frequently Asked Questions

What is a .list file?

A .list file is a LIST file.

What are the magic bytes for .list files?

The magic bytes for LIST files are 54 68 69 73 20 69 73 20 54 65 58 2C at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.

How do I validate a .list file?

To validate a .list file, read the first bytes of the file and compare them against the known magic bytes (54 68 69 73 20 69 73 20 54 65 58 2C) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.

What is the MIME type for .list files?

The primary MIME type for .list files is text/plain.

Is it safe to open .list files?

LIST (.list) 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.
