The magic bytes for ZIPX files are 50 4B 03 04 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .zipx file?
To validate a .zipx file, read the first bytes of the file and compare them against the known magic bytes (50 4B 03 04) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .zipx files?
