I would try something like this:

Try
  File.writeString( File.DirApp, "test.csv","lore ipsum...")
Catch
  Log(LastException)
End Try

Thanks. It works but it is strange that there is no standalone command for that action.

This is something that javafx wont be able to detect. It happens at OS level. You sould try calling an external exe with jshell such as this one http://www.nirsoft.net/utils/opened_files_view.html with the /FileFilter switch.
