Why do in-memory realms spawn a file-extension-less realm file on windows desktop?

Title pretty much sums up everything I want to say 😄 getting a realm instance with an InMemoryConfiguration creates a realm file in the documents folder here on Windows 10.

This file is used as swap in case the data in the Realm can't fit in the computer's memory. Most of the time it should be completely empty though, unless you're working with massive amounts of data. It should also be deleted when you close the last instance referencing it.

Here's a similar issue in the Cocoa repository where Alex and JP go into a little bit more detail.
