It is typically used by specific desktop or industrial programs to preserve project settings, configuration records, or other program-specific assets. Because support is limited and the format is rarely documented, files should be opened only in trusted software; the format itself is generally low risk, but compatibility may be poor.","mime":[],"risk_level":"Safe","signatures":[{"hex":"55 55 AA AA","offset":0,"sources":[{"name":"Wikipedia","url":"https://en.wikipedia.org/wiki/List_of_file_signatures"}]}],"related":[],"usage":{"python":"def is_pcv(file_path: str) -> bool:\n    \"\"\"Check if file is a valid PCV by magic bytes.\"\"\"\n    signature = bytes([0x55, 0x55, 0xAA, 0xAA])\n    with open(file_path, \"rb\") as f:\n        return f.read(4) == signature","node":"function isPCV(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x55, 0x55, 0xAA, 0xAA]);\n  return buffer.subarray(0, 4).equals(signature);\n}","go":"func IsPCV(data []byte) bool {\n    signature := []byte{0x55, 0x55, 0xAA, 0xAA}\n    if len(data) < 4 {\n        return false\n    }\n    return bytes.Equal(data[:4], signature)\n}"}}}
