Multiple File Upload When Adding New User

I have a ASP.NET page with a Create New User Wizard.    Step 3 of the wizard I have some File upload fields and a upload button which successfully uploads the files into a "Upload" folder on the Hard Drive.   Also included in step 3 of the wizard is the Finish button which adds the new user information into  the table.

I need to make adjustments and am unsure how to proceed.  I  want that when the new user presses the upload button  or the Finish button a folder is created in a Upload folder within the root of the site. I want the folder name to be  ased upon the new user "USER NAME".   The new folder should contain the uploaded file for that user.  

I am attaching the code .
Thanks
