Difficult to download Sentinel-1 orbit files in SNAP

I used SNAP to do Sentinel-1 interferometry. It needs precise orbit files, but i found it took a very long time (more than one hour) in the step ‘Apply orbtit file’ due to, I think, the network connection problem. Can I download the orbit files mannually and put it in somewhere that SNAP can skip automatic download step? And in which folder i should put it in?

yes, this is possible - please check here:
