How to validate .otg files in Python

Python
def is_otg(file_path: str) -> bool:
    """Check if file is a valid OTG by magic bytes."""
    signature = bytes([0x50, 0x4B])
    with open(file_path, "rb") as f:
        return f.read(2) == signature

How to validate .otg files in Node.js

Node.js
function isOTG(buffer: Buffer): boolean {
  const signature = Buffer.from([0x50, 0x4B]);
  return buffer.subarray(0, 2).equals(signature);
}

How to validate .otg files in Go

Go
func IsOTG(data []byte) bool {
    signature := []byte{0x50, 0x4B}
    if len(data) < 2 {
        return false
    }
    return bytes.Equal(data[:2], signature)
}

Frequently Asked Questions

What is a .otg file?

A .otg file is a OTG file.

What are the magic bytes for .otg files?

The magic bytes for OTG files are 50 4B at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.

How do I validate a .otg file?

To validate a .otg file, read the first bytes of the file and compare them against the known magic bytes (50 4B) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.

What is the MIME type for .otg files?

The primary MIME type for .otg files is application/vnd.oasis.opendocument.graphics-template.

Is it safe to open .otg files?

OTG (.otg) 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.
