Mmm, these differences can be well due to the use of different filesystems in the different platforms. Also, even using the same filesystem, a different parametrization (i.e. different blocksizes) can lead to these diferences in file sizes. The best is to use the 'h5ls -rv' against your files and see the percentage of utilization in the "Storage:" field. This later method ensures the correct account of the used sizes on behalf of the HDF5 library. -- >0,0< Francesc Altet http://www.carabos.com/ V V Cárabos Coop. V.
