If this post answers your question or helps, please mark it as such.
I saw now when I red your answer that I have not give the right info. What I want to do is a file browser that browses the web server, not the local hard drive. I have a .NET browser today, but like to have a browser in AS.
Let's say a user has the usernamew susi. When the user register on the page a subfolder with the username is created. The user can upload and manage the files in a browser.
Hope you understand?
I have seen a couple of these on the net but no tutorial.
