Frequently Asked Questions
What is a .myi file?
A .myi file is a MYI file.
What are the magic bytes for .myi files?
The magic bytes for MYI files are FE FE 06 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .myi file?
To validate a .myi file, read the first bytes of the file and compare them against the known magic bytes (FE FE 06) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .myi files?
The primary MIME type for .myi files is application/x-mysql-misam-compressed-index.
Is it safe to open .myi files?
MYI (.myi) 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.
