@sharon

You mean I can read all the files under the same directory when user choose one file?

Yes

I am confused when user choose a directory, how can paraview know which reader to use?

And if i write my own reader, how can tell paraview to use my reader after user select certain directory?

Because for a file, there is a suffix to tell reader, but for a directory, how to know?

There is a pattern mechanism in the XML definition of the reader, see AMReX Particles Reader in readers.xml
