Frequently Asked Questions
What is a .mdo file?
A .mdo file is a MDO file.
What are the magic bytes for .mdo files?
The magic bytes for MDO files are 54 68 69 73 20 69 73 20 54 65 58 2C at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .mdo file?
To validate a .mdo file, read the first bytes of the file and compare them against the known magic bytes (54 68 69 73 20 69 73 20 54 65 58 2C) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .mdo files?
The primary MIME type for .mdo files is text/plain.
Is it safe to open .mdo files?
MDO (.mdo) 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.
