Files in series named only with numbers are not recognized as a group.
From https://discourse.paraview.org/t/reading-time-series-where-file-name-is-just-number/10105/2
I’m looking at some older scivis contest data, and the data contains many file time series with files named like 000.vtu, 001.vtu, 002.vtu, 003.vtu,…
I expected the ParaView file browser to recognize these files as a series and group them together so that I could load the group and play them as a time series. But I was surprised to find that ParaView does not group files like this. Apparently, if the file is only a number, it will not be grouped.
This is a bug.
