I'm working on an embedded project that has no file system, and our kludge of a database has ballooned in functionality. It's now so inefficient, we can't stand it any longer.

I'm trying to figure out if there's built-in support for a flat file system in SQLite. I've dug around http://sqlite.org for a while now, but haven't found anything specifically covering it. Has anyone found a supported implementation written in C? It seems like such a straightforward request, but I can't find anything written about it.

We have plenty of memory available. In a perfect world, I'd like to just set aside a large portion of it, pass the FS a pointer, then let the FS/SQLite library just use what it wants.
