Java SE (Java Platform, Standard Edition)

Hello all
Class : javax.swing.JFileChooser (network folders)
J2SE : 1.4
OS : Windows

I'm in need of urgent help for JFileChooser, scenerio is, currently when I do a open or save dialog using the JFileChooser it brings up the mapped network folders along with local folders on my PC.

For selection, if I clicked on the network folders, is there a way I could differentiate if it was one of the mapped network folders or a regular file on the file system? I dont see any of the folders underneath my network folder, it just doesnt seem to work right.

Also the mapped network folder is username password protected which comes up with the Username Password prompt dialog the first time I access it through the open / save dialogs, where exactly does it store this information.

Any help would be highly appreciated.

Regards
