List the Drives in Windows

I am trying to use a TreeTable with FileSystemContainer. When I call

FilesystemContainer files = new FilesystemContainer( new File( "/" ), fileFilter, false );​

​in Windows it seems to show the contents of c:. How can I make it show a list of all currently mounted volumes?

I found this

File[] roots = File.listRoots();
for(int i=0;i<roots.length;i++)
:" + roots[i]

So the question now is if I can load a TreeTable with the results of File.listRoots() and then if/when someone expands it, load the child node with a FileSystemContainer withe appropriate drive as a root directory…
