i was proposing a pointer, which could be nil.
i would put the pointer where the file name should
be—perhaps by setting the first 8 bytes to non-unicode
magic and the next 8 bytes to a pointer to the
direct name block.
so why not change nothing. the first 8180 bytes go
in the first direct block anyway.
btw, i have far fewer large files than you, but still 25%
of the ones bigger than 6112 bytes are smaller than
8180
