Erm a tree of file directory?

a small example for you. if you want to list the files of an directory follow this steps:

1. set your fileChooser to: fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);

2. Walk in an recursion through this selected Directory and at it to the filelist.

have fun, marcel
