Re: Tree Recursion for Copy Paste overwrite

Sorry, Mike, I wasn't very clear with my issue.

In Windows Explorer, suppose I have a tree structure with the folders
'MyFolderA' and 'F1' at the same level.  Suppose that 'MyFolderA' also
has a folder underneath it called 'F1'.  If I copy the folder 'F1' that
is at the level 'MyFolderA' into 'MyFolderA', I get a message that the
folder 'F1' already exists asking me if I'd like to overwrite any files
or folders underneath the existing 'MyFolderA-->F1' with the ones I am
pasting.

What I can't figure out is how to do this 'overwriting' from a 'travel
through the treenode' standpoint...

I'm not sure I understand the question.
When you paste a new folder in explorer that you have copied from a
previous
location, it renames the top-level folder so that it is unique with a
"Copy
of XXXX" folder.
