How to validate .tsp files in Python

Python 
def is_tsp(file_path: str) -> bool:
    """Check if file is a valid TSP by magic bytes."""
    signature = bytes([0x4D, 0x5A])
    with open(file_path, "rb") as f:
        return f.read(2) == signature

How to validate .tsp files in Node.js

Node.js 
function isTSP(buffer: Buffer): boolean {
  const signature = Buffer.from([0x4D, 0x5A]);
  return buffer.subarray(0, 2).equals(signature);
}

How to validate .tsp files in Go

Go 
func IsTSP(data []byte) bool {
    signature := []byte{0x4D, 0x5A}
    if len(data) < 2 {
        return false
    }
    return bytes.Equal(data[:2], signature)
}

Frequently Asked Questions

What is a .tsp file?

A .tsp file is a TSP file. DOS MZ executableand its descendants (includingNEandPE)

What are the magic bytes for .tsp files?

The magic bytes for TSP files are 4D 5A at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.

How do I validate a .tsp file?

To validate a .tsp file, read the first bytes of the file and compare them against the known magic bytes (4D 5A) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.

What is the MIME type for .tsp files?

There is no officially registered MIME type for .tsp files. Systems typically use application/octet-stream as a generic fallback when handling this format.

Is it safe to open .tsp files?

TSP (.tsp) 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.
