Just because it's legacy, doesn't mean it's not a powerful tool.

Files have multiple advantages over other approaches, such as being independent from the application that created them (even if the company subsequently goes under), being editable with a different application from the one that created them (though imperfectly sometimes), and being self-contained bundles of data that need no infrastructure to support them other than a local application (compared to other approaches, where a large cloud infrastructure is basically mandatory and you're SOL if it goes away for you).

Recency bias is a thing. Try to work counter to it.
