Open large HDF5 file (12.5GB) using HDFView 2.14

I have a very large 12.5GB HDF5 file, written using Python/ h5py with chunked data enabled (chunks=True) for all datasets.

I cannot open the file using HDFView 2.14- when I try open it, nothing happens. I thought it may be a memory error, but there is no error message and the program does not crash, just the file does not open.

Any suggestions on how I can open/ view the file? It contains just 5 datasets, however each dataset contains around 778 million rows… hence the problem.

Thank you!
