Two copies of the data will be stored locally (original and hdf),\nbut will significantly speed up loading files.\n\nTo enable this option, make sure PyTables is installed using::\n\n  pip install pytables\n\nAnd then edit your heliopyrc file to enable hdf file saving\n(see :doc:`/guide/configuring` for more information).\n\nTo check how much data is stored in both it's original format and hdf format\nsee `sphx_glr_auto_examples_data_inventory.py`.\n"
