Hello there!
I need to delete a folder or a file in a directory using vb.net. The folder and file will be deleted when this file is added to another folder. Therefore, the existing file will be deleted from the old folder. And the old folder will be deleted if the file is the last file in that folder.

Thanks alot for your help.

Directory Class: System.IO Namespace

method Exists - first check if directory exists
mothid Delete - delete directory.
