Jonathan,
Used() works for aliases only and it only detects current datasession. It might be in use in another private datasession with that alias same as filename. Within the same session I never encountered it returning wrong info, do you have reproducing code ?
Your strategy would mostly depend on what you're trying to do.
You can use DE even if the file location changes. Check for messages about it in last 1-2 months. Keyword might be 'updateDE'.
