From 4501585:
12) configure windows to show all files, even the hidden files (to do this
    under windows 2000 open "My Computer", select the "Tools" menu and then
    select "Folder Options". there you'll find the option to show hidden files)

    now open the native windows file chooser, go to C:\ and look at the hidden
    files: they are the ones with the light coloured icon.

    now open JFileChooser and go to C:\ and look the hidden files.... ops!
    they aren't shown at all. so what I can do to select an hidden file?
