{"success":true,"data":{"ext":"vmdk","name":"VMware 4 Virtual Disk description file","description":"VMware 4 Virtual Disk description file (VMDK) is a descriptor format created by VMware and used to define the layout and metadata of a virtual disk. It is used by VMware virtualization products to describe virtual machine storage, including split disks, snapshot chains, and disk geometry settings. The format is generally safe, but like other virtual disk files it should be obtained from trusted sources because it may reference large companion disk data files or external paths.","mime":["application/x-vmdk"],"risk_level":"Safe","signatures":[{"hex":"4B 44 4D","offset":0,"sources":[{"name":"Wikipedia","url":"https://en.wikipedia.org/wiki/List_of_file_signatures"},{"name":"Gary Kessler","url":"https://www.garykessler.net/library/file_sigs_GCK_latest.html"}]},{"hex":"23 20 44 69 73 6B 20 44 65 73 63 72 69 70 74 6F","offset":0,"sources":[{"name":"Wikipedia","url":"https://en.wikipedia.org/wiki/List_of_file_signatures"},{"name":"Gary Kessler","url":"https://www.garykessler.net/library/file_sigs_GCK_latest.html"}]},{"hex":"43 4F 57 44","offset":0,"sources":[{"name":"Gary Kessler","url":"https://www.garykessler.net/library/file_sigs_GCK_latest.html"}]},{"hex":"4B 44 4D 56","offset":0,"sources":[{"name":"Gary Kessler","url":"https://www.garykessler.net/library/file_sigs_GCK_latest.html"}]}],"related":["vhd","adf","dmg","bin","iso","toast"],"usage":{"python":"def is_vmdk(file_path: str) -> bool:\n    \"\"\"Check if file is a valid VMDK by magic bytes.\"\"\"\n    signature = bytes([0x4B, 0x44, 0x4D])\n    with open(file_path, \"rb\") as f:\n        return f.read(3) == signature","node":"function isVMDK(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x4B, 0x44, 0x4D]);\n  return buffer.subarray(0, 3).equals(signature);\n}","go":"func IsVMDK(data []byte) bool {\n    signature := []byte{0x4B, 0x44, 0x4D}\n    if len(data) < 3 {\n        return false\n    }\n    return bytes.Equal(data[:3], signature)\n}"},"category":"Disk Images"}}
