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