Robert, Sorry I missed the email earlier. What you have as an alternative is indeed a reasonable approach. Once can also use ParaView's infrastructure used by the file dialog, but it's a little clunky currently, since it needs to be pythonified for easier user.
Here's how you'd do this with 5.4.1. from paraview import servermanager as sm helper = sm.misc.FileInformationHelper() helper.DirectoryListing = 1 helper.WorkingDirecotry = "'/path/to/data/on/remote" pvinfo = servermanager.vtkPVFileInformation() helper.GatherInformation(pvinfo) for a_pvinfo in pvinfo.GetConents(): if a_pvinfo.GetType() == a_pvinfo.FILE_GROUP: for b_pvinfo in a_pvinfo.GetContents(): assert b_pvinfo.GetType() == b_pvinfo.SINGLE_FILE print (b_pvinfo.GetName(), b_pvinfo.GetFullPath()) elif a_pvinfo.GetType() == a_pvinfo.SINGLE_FILE print (a_pvinfo.GetName(), a_pvinfo.GetFullPath()) This will print all files in the directory. See vtkPVFileInformation docs (https://www.paraview.org/ParaView3/Doc/Nightly/www/cxx-doc/classvtkPVFileInformation.html) for more API details. Hope that helps.
