You cannot open this specific file ( .002 ) on its own. To extract the content, you must have all parts of the set (e.g., .001 , .002 , and so on) in the same folder. How to Open It

You will need a program like 7-Zip for Windows, or apps like Unzip One or the built-in Finder on macOS to extract them.
