Hi Marcelo,
the sharing is easy; your Ubuntu WSL on Windows 10 will be stored at C:\Users$YOURUSERNAME\AppData\Local\Packages\CanonicalGroupLimited.Ubuntu20.04onWindows_79rhkp1fndgsc\LocalState\rootfs
or something similar like this… Be aware I have version Ubuntu 20.04, but I don’t know which version you have…
If you would like to launch paraview directly from Ubuntu WSL the first step is launch xLaunch application on your windows and as second step launch paraview from your comand line…
But as Mathieu mentioned - the easiest way is using Paraview for Windows… It works very well…
