.h5 file takes too much time to open

Question

When I try to open .h5 file (size: 750 mb) it takes too much time. And I don't know if it's a problem with ArcGis, as it just keeps showing progress bar. I've been waiting for this file to open for 5 hours now and it didn't finish. Is it supposed to be that long or is it probably because the file is damaged?

P.S. on task manager I can see that ArcGis is working and doing something.

It's locally stored. I just go to Map > Add Multidimensional raster and then browse my .h5 file. Yesterday I left it loading, it has been loading for 24 hours now... And ... NOTHING...
