Opening HDF5 file with command line

Would you be willing to share your issue and the solution here briefly, in case others have a similar problem?

My error was to put the option /I in

HDF5OpenFile /I /R fileID as "c://temp//test.hdf5"

Even if one indicates the complete file path, the option /I opens a prompt window to search for the file. The correct command is simply

HDF5OpenFile /I /R fileID as "c://temp//test.hdf5"

Of course, the variable fileID must be defined first with a Variable fileID.
