Help reading common data format (.cdf) files

Can Igor read .cdf files, and if so, how does one do that? I have found some documentation about netCDF files (.nc) but that doesn't help me load .cdf files, at least as far as I can tell.

Thanks in advance.

And in case your CDF has datatypes which netcdf3 classic lacks, you can also convert it to netcdf v4 which is a plain HDF5 file.
