# xarray.backends.H5netcdfBackendEntrypoint

### *class* xarray.backends.H5netcdfBackendEntrypoint[[source]](https://github.com/pydata/xarray/blob/main/xarray/backends/h5netcdf_.py#L498-L736)

Backend for netCDF files based on the h5netcdf package.

It can open “.nc”, “.nc4”, “.cdf” files but will only be
selected as the default if the “netcdf4” engine is not available.

Additionally it can open valid HDF5 files, see
[https://h5netcdf.org/#invalid-netcdf-files](https://h5netcdf.org/#invalid-netcdf-files) for more info.
It will not be detected as valid backend for such files, so make
sure to specify `engine="h5netcdf"` in `open_dataset`.
