Thanks for your response Thom,
As for uploading whole file/folder structure, I think we have to followup
the FTP protocol rules, create folder on the serverside first then use
upload command to upload files .... FtpWebRequest is just a raw component
which implement those basic FTP verbs. Maybe some 3rd party guys will
implement a encapsulated one which provide a uploading/downloading folder
strucure fuctionality.. I think your current application is just
something like a simple GUI WYSIWYG ftp client, yes? I think most such
FTP client application just using the basic FTP commands(upload file, make
folder...) to implement complex operations(folder structure upload...).
Thanks & Regards,
Steven Cheng

| Thanks for the help.
|
| My final project in this area has probably already been done elsewhere.
I

| 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.
