|
| Thanks for the help.
|
| My final project in this area has probably already been done elsewhere. 
I
| want to download or upload a complete tree structure.  This will delete
| everything on the receiving end and then transfer the entire structure.
|
| The challenge is coming up with the recursive technique.
|
| Any leads would be appreciated.
