"What exists is a way to name a non-volatile data set."
1. What if it's "code" not "data"? I thought "data" in this case was just 1's and 0's, i.e. what the represent, e.g. electric charges on a medium? I thought that how we interpret these charges is what makes them "code" or "data".
2. What if the "file" is stored on a "RAM disk"? Is that non-volatile? If no, then does that mean this is not, by your definition, a "file"?
