In Swing's JFileChooser, the local drives are accessible but not the mapped network drives (on Windows platform). How can I see the network drives?

First of all I do think that JFileChooser does show the network drive if it was mapped (i.e. has a drive letter) before the JFileChooser was created.

What it does not show is the UNC based names like emote_machine emote_share_name or the network neighbourhood.
