Nokia PC Suite Content Copier file magic bytes (.nfc)

.nfc file signature: 03 00 00 00 | application/octet-stream

Nokia PC Suite Content Copier file is a legacy backup file format created for Nokia PC Suite, a desktop application maintained by Nokia for managing compatible mobile phones. It was used to store contacts, messages, settings, and other phone data for transfer or restoration between a handset and a computer. The format is associated with older Nokia software and devices, so support is largely historical; as with any backup file, it should be opened only from trusted sources.

Validation Code

How to validate .nfc files in Python

Python
def is_nfc(file_path: str) -> bool:
    """Check if file is a valid NFC by magic bytes."""
    signature = bytes([0x03, 0x00, 0x00, 0x00])
    with open(file_path, "rb") as f:
        return f.read(4) == signature

How to validate .nfc files in Node.js

Node.js
function isNFC(buffer: Buffer): boolean {
  const signature = Buffer.from([0x03, 0x00, 0x00, 0x00]);
  return buffer.subarray(0, 4).equals(signature);
}

How to validate .nfc files in Go

Go
func IsNFC(data []byte) bool {
    signature := []byte{0x03, 0x00, 0x00, 0x00}
    if len(data) < 4 {
        return false
    }
    return bytes.Equal(data[:4], signature)
}
