I guess I'll have to try some practical tests to see whether the amount of wasted space is small enough for this approach to be acceptable to us or not.

I've found the documentation for this function... I also found a couple documents here with more detailed and higher-level descriptions, for which I'll post a link for the sake of anyone else looking for this info: https://support.hdfgroup.org/HDF5/docNewFeatures/FileSpace/ I'll spend some time looking at these. Are these documents accurate with respect to the library (as of 1.10.1) ? Or is there a more up-to-date version that I should look at? Thanks again, -- Kevin B.
