I must admit I'm not familiar with dirfiles at all, so maybe this is a
stupid suggestion, but you could use CDF or netCDF to store data in a
very compact binary format even when all fields don't have the same
length. There is support for reading CDF/netCFD in kst, and open-source
libraries to write them. To me, they look like a pretty good way to
archive data in a compact and efficient manner.
