Success! I needed only one volume. Window 10 ( or may be my work place firewall) created some some hiccups. It would tell in the middle of execution that "wget has stopped working" . I started the program 4 times  and thanks to wget robustness each time it started where it had left. (got volume 3448, 1.83GB).

I use these datasets.  CTX has a data volume of >10TB, while MARCI is closer to around 1TB (significant rounding involved in these numbers).  That is just the real data - the .IMG files.  Add to that all the preview/browse data and you need more space.  As of PDS release 51, CTX has around 106,000 .IMG files, and MARCI is the same to within 1000-2000.

<p>There are several files. I think that they all needs to downloaded to have the complete dataset. Is there a particularly good way to download them all in one shot?</p>

How can I download all of this JPL MRO imaging data at once?

You can do it, I will leave you to decide whether you should... As an experiment, I downloaded the mrox_3374 subdirectory of files and the result came out to 3.7 GB. Assuming the other 99 "volumes"/directories are the same, this multiplies out to 370 GB.
I downloaded these data using wget which is a standard utility on Unix/Linux and Mac computers. It is also available for Windows systems; this Wget for Windows 10 tutorial should be of some help in getting it installed and going.
Once this is installed you can do:
wget -np -nH -c --cut-dirs 4 -r https://pds-imaging.jpl.nasa.gov/data/mro/mars_reconnaissance_orbiter/ctx/mrox_3374/

The key flags are -r which means recurse into directories, -np which means don't ascend to the parent directory (to stop it sucking down the entire website), -c which will continue the transfer if it fails and you restart the wget and the --cut-dirs 4 which cuts 4 levels of the directories off the recursive download (the data/mro/mars_reconnaissance_orbiter/ctx parts)
If you really, really want to suck down the whole thing you could do:
