How to validate .vcd files in Python

Python 
def is_vcd(file_path: str) -> bool:
    """Check if file is a valid VCD by magic bytes."""
    signature = bytes([0x45, 0x4E, 0x54, 0x52, 0x59, 0x56, 0x43, 0x44, 0x02, 0x00, 0x00, 0x01, 0x02, 0x00, 0x18, 0x58])
    with open(file_path, "rb") as f:
        return f.read(16) == signature

How to validate .vcd files in Node.js

Node.js 
function isVCD(buffer: Buffer): boolean {
  const signature = Buffer.from([0x45, 0x4E, 0x54, 0x52, 0x59, 0x56, 0x43, 0x44, 0x02, 0x00, 0x00, 0x01, 0x02, 0x00, 0x18, 0x58]);
  return buffer.subarray(0, 16).equals(signature);
}

How to validate .vcd files in Go

Go 
func IsVCD(data []byte) bool {
    signature := []byte{0x45, 0x4E, 0x54, 0x52, 0x59, 0x56, 0x43, 0x44, 0x02, 0x00, 0x00, 0x01, 0x02, 0x00, 0x18, 0x58}
    if len(data) < 16 {
        return false
    }
    return bytes.Equal(data[:16], signature)
}

Frequently Asked Questions

What is a .vcd file?

A .vcd file is a VideoVCD file. VideoVCD (GNU VCDImager) file

What are the magic bytes for .vcd files?

The magic bytes for VideoVCD files are 45 4E 54 52 59 56 43 44 02 00 00 01 02 00 18 58 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.

How do I validate a .vcd file?

To validate a .vcd file, read the first bytes of the file and compare them against the known magic bytes (45 4E 54 52 59 56 43 44 02 00 00 01 02 00 18 58) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.

What is the MIME type for .vcd files?

There is no officially registered MIME type for .vcd files. Systems typically use application/octet-stream as a generic fallback when handling this format.
