Is it still not clear that reinventing the wheel here is not a
productive idea? Because that's what you're doing. You're reinventing a
filesystem on top of a filesystem. Hundreds of thousands of man hours
have gone into refining and optimizing filesystem efficiency in Linux
and BSD and *cough* other operating systems, based upon decades of
accumulated research and experience in the field of computer science.

Dealing with thousands (Come on now, my entire 95% full 250gb disk has
about a million files on it *total*) of independent textures quickly and
efficiently is exactly the kind of thing filesystems are *designed for*.
