Creating and deleting a directory is very important for a community website
where a user posts articles, forum messages etc. When the user registers for
a website then that folder can be created dynamically and after that the data
can be automatically placed inside their own directory instead of the root or
anywhere else. Creating a directory is a very easy task; we just require the
namespace System.IO and a couple lines of code. Here you go:
