HDF5 file extension - Hierarchical Data Format

What is hdf5 file? How to open hdf5 files?

File type specification:

Various data file type icon Various data file type

The hdf5 file extension is one of the several suffixes used for files in the Hierarchical Data Format.

HDF is the name of a set of file formats and libraries designed to store and organize large amounts of numerical data originally developed at the National Center for Supercomputing Applications.

This hdf5 file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.

Help how to open:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert:

As far as we know, this .hdf5 file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
