Hi, does anyone know how to use files (extension .sha512) from [VTKData-9.0.3.tar.gz](https://www.vtk.org/files/release/9.0/VTKData-9.0.3.tar.gz) ?  
Thanks,  
Ricardo

In my opinion, this " .sha512" file can not used for application test, it just used to check the real data’s Data integrity which used for application test.

@Ricardo_M_Picado SHA512 files are content links; they are associated to an actual data file (e.g. a PNG image, an STL file, etc.) hosted in a specific data hosting service. They are used (i) to separate the code from the data, and (ii) to avoid having excessively large files within a code repository.

Note sure if all information here is up-to-date, but it certainly gives you a better picture about VTKData:

HTH.

I just want to run online [VTK examples like this one](https://kitware.github.io/vtk-examples/site/Cxx/VisualizationAlgorithms/ProbeCombustor/) - but cannot find a simple description of how to obtain the necessary data files. The [link referenced above](https://gitlab.kitware.com/vtk/vtk/-/blob/master/Documentation/dev/git/data.md) seems to apply to VTK contributors, and the procedure seems quite complex. How to just get the data files to run the examples?
