It is used in compatible Sony digital voice recorders, cameras, and portable devices for dictation, voice notes, and short spoken recordings. The format is largely legacy and is generally safe to open, though playback support may be limited in modern software and often requires Sony-compatible applications.","mime":[],"risk_level":"Safe","signatures":[{"hex":"4D 53 5F 56 4F 49 43 45","offset":0,"sources":[{"name":"Gary Kessler","url":"https://www.garykessler.net/library/file_sigs_GCK_latest.html"}]}],"related":["dvf"],"usage":{"python":"def is_msv(file_path: str) -> bool:\n    \"\"\"Check if file is a valid MSV by magic bytes.\"\"\"\n    signature = bytes([0x4D, 0x53, 0x5F, 0x56, 0x4F, 0x49, 0x43, 0x45])\n    with open(file_path, \"rb\") as f:\n        return f.read(8) == signature","node":"function isMSV(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x4D, 0x53, 0x5F, 0x56, 0x4F, 0x49, 0x43, 0x45]);\n  return buffer.subarray(0, 8).equals(signature);\n}","go":"func IsMSV(data []byte) bool {\n    signature := []byte{0x4D, 0x53, 0x5F, 0x56, 0x4F, 0x49, 0x43, 0x45}\n    if len(data) < 8 {\n        return false\n    }\n    return bytes.Equal(data[:8], signature)\n}"}}}
