I'll check out this one, but the others I looked at all had significant
restrictions (only 1 file open, inability to open multiple files with a
shared buffer, etc. My tuned copy of FatFS can open multiple files on
multiple drives/partitions and share 1 512 byte block of RAM among all
the files. You can turn LFN support off at compile time, if you don't
need or want it.

np. It's optional to compile in, as some people want the single buffer
option without LFN support.

Yeah, that's gonna be tight. The uIEC/SD2IEC bootloader is 4K, and it's
all we can do to cram FAT (no LFN) and physical access routines in there.
