I have a file of strings like c:\acad\j\loop\unit-30.  I would like to build a tree from them without duplicating any nodes. The first node would be "c:", the second would be "acad" and so on.  The next string would be "c:\acad\j\loop\unit-31".  I don't want to have another level 1 node of "c:", In this case I would just like to add "unit-31" to the loop node as a child.

You atart at level one all the time...compare c: to everything at level one, if it exists, then go to level two off of that node, if it doesn't exist, then add it.  At level two you check to see if there is already a level two that matches the level two you are looking for, if so, then go to its level 3, if not add it.

I can't figure out how to do the compare.  Do I you something like this.  If CurrentSubdirectory (c:) <> treeview1.node.text then addchild(CurrentSubdirectory)?  I still can't figure out how to access the properties of the class and what properties there are.  Also I can't figure out how to do the methods and I think I should be able to make a new class and add some more properties and methods.
