Hai! Everybody!

    I am working for a Swing project. My module is to create
MyComputer Frame same as the windows MyComputer Explorer with the same
functionality. I have to access the drives of my system  and display
the contents as folders.

  1.  I got the tree structure with my drives and contents, but when I
click the nodes of the tree the contents of that folder has to be
displayed.How can I achieve it?

 2.  I have to add a treestructure to the JComboBox, which is same as
the MyComputer Addressbar. But the ComboBox constructor is not
accepting the tree object as a parameter.

3. After that I have to create an empty  folder from my java program
to store any thing with some memory allotted to it.

 Can anybody give any suggession to me? How can I interact with
Operating System and get the same contents?
