asp.net-mvc - MVC Uploading,File Management

Question

Using vs'12, internet Application Template, asp.net MVC4 C# with Kendo UI and Razor Views

In My Controller

Curious on why it won't allow me to create a Folder, then why it won't let me save to anywhere but a "Server MapPath"

1. Why not?
2. Whats the workaround? / the Right way to manage Files ( documentation would suffice )
3. Why can you only upload 29 images at same time, yes maxRequestLength="2097151" is set 29 works fine and fast, 30 takes 5 minutes and displays "The connection was reset"

Answer 1

Are you debugging the application with IIS? If yes then the default application pool will be used and it will not have full permission to manage file system on desired location. The better way you should create app-pool with account to whom you can provide appropriate file management permission.
