Hello

I am new in this list and in HDF5.  
I have already written a program creating simple HDF5 files using hdf5-1.6.10-1.el5 on RHEL5.  
I create one hdf file every day, and want to create a new one every minute that includes the daily one plus other groups.  
What kind of solutions are available?  
It can be a command line or C programming.  
Thanks for any help
