well ... you can use the File-class, starting from your root (this could for instance be C:/) and then use a recursive method that returns the result of the listFiles method of the File class.

is this supposed to be an answer to the OP's question? if so, recursion is possible.
but somehow I think this is more about advertising your own project for some reason.
