Interesting. The header size seems big for low-resources embedded systems (e.g. with only 256 bytes of EEPROM). I'd rather use a file identifier (e.g. a 8-bit number) to identify what a file is doing instead of arbitrary names.

I feel like with less than 1000 bytes the situations where you wouldn't want to directly manage every byte are quite rare. What is your project?
