Hmmm... how?
Your app is going to index that and won't care what format the file
is, and there are advantages to multiple files.
It might be better if you want to parse a single file, especially if
you want a lot of internal structure. For example, configuration
files, documents, etc.
But for stuff that needs to scale, the overhead of multiple indexed
files quickly pays off, and it seems that's still what people use.

Aren't you comparing a good XML implementation with a really bad fixed
field implementation?
We've been doing multi-level relational with fixed field and
extendable fixed field records for 40 years and it seems to work
pretty well, and is still the basis of most database file formats.
