This is actually an interesting example. To me it sounds like it actually should be less confusing to a person who has no preconceived notion of what a file should be, and only wants to save their work and reopen it later, not worried about what shape the saved object takes.

On that note, I remember how absolutely ecstatic I was when I first set up Sublime Text and discovered that unsaved editor tabs always reliably survive restarts; it essentially flips the script, whereby I've lost multiple saved files by accidentally deleting them, but I've never accidentally lost work in unsaved tabs, and I've never actually had any interest in figuring out where and how these tabs get persisted - it just works.
