Congratulations on locating yet another function call that has absolutely nothing to do with this thread.

So I take it you're not going to admit when you're wrong?

The fact is, file IO is not optimized. Directory searching, fat searching and file IO are not using these calls. They are using single sector (or potentially cluster) reads/writes.

If you had actually "optimized for reading" you'd know this.
