Frequently Asked Questions
What is a .sda file?
A .sda file is a SDA file.
What are the magic bytes for .sda files?
The magic bytes for SDA files are D0 CF 11 E0 A1 B1 1A E1 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .sda file?
To validate a .sda file, read the first bytes of the file and compare them against the known magic bytes (D0 CF 11 E0 A1 B1 1A E1) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .sda files?
The primary MIME type for .sda files is application/vnd.stardivision.draw.
Is it safe to open .sda files?
SDA (.sda) 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.
