title: How to create a property store binary file
body: <p>I'm trying to implement an icon-based property in Windows File Explorer, and my understanding from <a href="https://stackoverflow.com/a/47804200/9567282">this</a> post is that it requires returning a <em>property store binary file</em> from the property handler.  Does anyone know how to create a property store binary file?  After searching, I've come across some <a href="https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-propstore/39ea873f-7af5-44dd-92f9-bc1f293852cc" rel="nofollow noreferrer">documentation</a> on the specification, but I don't see any examples of how to create one.  Thank you very much.</p>
