Hi all,
There was a time where I could checkout/download [VTKData](https://www.vtk.org/files/release/9.0/VTKData-9.0.1.tar.gz) and [VTKLargeData](https://www.vtk.org/files/release/9.0/VTKLargeData-9.0.1.tar.gz) to have some sample datasets to play around with. I’ve downloaded the links from the download page but I’m not quite clear on how to get the data after extracting them. The contents of the archives are some hidden directories `.ExternalData` which contains a `SHA512` directory with many varying sized files but the names are not human-readable…Am I going about this the wrong way?

These tarballs are the data stores for use in an offline build. [This issue](https://gitlab.kitware.com/vtk/vtk/-/issues/18154) tracks adding tarballs with the files “in location” for easier use by non-build-systems.
