Yes, that is exactly how we are accessing the files. So if we use the core VFD for the file writes, the metadata will be cached in memory and only written at file close, like Mark described? And it will be written in one large, contiguous piece? Thanks Mark _______________________________________________ Hdf-forum is for HDF software users discussion.
