How to validate .dump files in Python

Python

def is_dump(file_path: str) -> bool:
    """Check if file is a valid DUMP by magic bytes."""
    signature = bytes([0x23, 0x20, 0x54, 0x68, 0x69, 0x73, 0x20, 0x69, 0x73, 0x20, 0x61, 0x20, 0x73, 0x68, 0x65, 0x6C, 0x6C, 0x20, 0x61, 0x72, 0x63, 0x68, 0x69, 0x76, 0x65])
    with open(file_path, "rb") as f:
        return f.read(25) == signature

Frequently Asked Questions

What is a .dump file?

A .dump file is a DUMP file.

What are the magic bytes for .dump files?

The magic bytes for DUMP files are 23 20 54 68 69 73 20 69 73 20 61 20 73 68 65 6C 6C 20 61 72 63 68 69 76 65 at byte offset 10. These bytes uniquely identify the file format regardless of the file extension.

How do I validate a .dump file?

To validate a .dump file, read the first bytes of the file and compare them against the known magic bytes (23 20 54 68 69 73 20 69 73 20 61 20 73 68 65 6C 6C 20 61 72 63 68 69 76 65) at offset 10. This is more reliable than checking the file extension alone, as extensions can be renamed.

What is the MIME type for .dump files?

The primary MIME type for .dump files is application/octet-stream.

Is it safe to open .dump files?

DUMP (.dump) 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.
