Frequently Asked Questions
What is a .wk2 file?

What are the magic bytes for .wk2 files?
The magic bytes for WK2 files are 00 00 02 00 06 04 06 00 08 00 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .wk2 file?
To validate a .wk2 file, read the first bytes of the file and compare them against the known magic bytes (00 00 02 00 06 04 06 00 08 00) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .wk2 files?
