[Paraview] How PV detects valid file formats?

[Nehme Bilal]

Dave,

Are you saying that can CanReadFile  is called even before the file is
selected ! ?
Fred is saying that his file is not showing up at all, so if
CanReadFile is called only after the file has is selected,
his problem is not releated to CanReadFile.
