problems downloading PARAVIEW training datasets

Hello.

I’ve downloaded PARAVIEW desktop for the Mac Pro running OSX Big Sur 11.5.1.
I’ve also downloaded the documentation and test datasets in both .zip and .tar archival formats.

The documentation downloads fine, but the test datasets produce folders without any datasets inside them. Could it be the extractor software I’m using? If so please advise the best app to de-archive on a Mac.

Thanks,
Cal Hisley

I just downloaded and extracted ParaViewTestingDataFiles from https://www.paraview.org/download/ without any issues.
