How to validate .w60 files in Python

Python 
def is_w60(file_path: str) -> bool:
    """Check if file is a valid W60 by magic bytes."""
    signature = bytes([0x61, 0x70, 0x70, 0x6C, 0x69, 0x63, 0x61, 0x74, 0x69, 0x6F, 0x6E, 0x2F, 0x76, 0x6E, 0x64, 0x2E, 0x77, 0x6F, 0x72, 0x64, 0x70, 0x65, 0x72, 0x66, 0x65, 0x63, 0x74, 0x3B])
    with open(file_path, "rb") as f:
        return f.read(28) == signature

How to validate .w60 files in Node.js

Node.js

  const signature = Buffer.from([0x61, 0x70, 0x70, 0x6C, 0x69, 0x63, 0x61, 0x74, 0x69, 0x6F, 0x6E, 0x2F, 0x76, 0x6E, 0x64, 0x2E, 0x77, 0x6F, 0x72, 0x64, 0x70, 0x65, 0x72, 0x66, 0x65, 0x63, 0x74, 0x3B]);
  return buffer.subarray(0, 28).equals(signature);
}

How to validate .w60 files in Go

Go

Frequently Asked Questions

What is a .w60 file?

A .w60 file is a W60 file.

What are the magic bytes for .w60 files?

The magic bytes for W60 files are 61 70 70 6C 69 63 61 74 69 6F 6E 2F 76 6E 64 2E 77 6F 72 64 70 65 72 66 65 63 74 3B at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.

How do I validate a .w60 file?

To validate a .w60 file, read the first bytes of the file and compare them against the known magic bytes (61 70 70 6C 69 63 61 74 69 6F 6E 2F 76 6E 64 2E 77 6F 72 64 70 65 72 66 65 63 74 3B) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.

What is the MIME type for .w60 files?

The primary MIME type for .w60 files is application/vnd.wordperfect.

Is it safe to open .w60 files?

W60 (.w60) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
