The directory is a linked list, starting with a pointer in track 11
sector 0.  Some of the 32-sector "unidos" formats point at track 11
sector 31 and count down to sector 1, effectively doubling the number
of files possible from 105 to 210 (IIRC).

Maximum possible is 50 tracks of 32 sectors, or 400K, unless you want
to change the structure of the VTOC sector and the code that reads it.
That would break pretty much everything though.
