The Global.asax:

The Global.asax file, also known as the ASP.NET application file, is an optional file that contains code for responding to application-level events raised by ASP.NET or by HttpModulesThe Global.asax file resides in the root directory of an ASP.NET-based application. At run time, Global.asax is parsed and compiled into a dynamically generated .NET Framework class derived from the HttpApplication base class. 

Mostly used for application and session start/end events and for global error handling.

The packages.config file:

The packages.config file is managed by the NuGet infrastructure. It is used to track installed packages with their respective versions. If we want to update our MVC 4 to MVC 5 then NuGet checked here of the previous version to replace by new one by creating their object.

 

The Web.config file:

ASP.NET MVC configuration is stored in Web.config files i.e. a XML file.

These files can appear in many directories in an ASP.NET MVC application. They help to configure application behavior even before after deploying, based on the fact that we can edit them with any text editor.

The web.config file exists in the Views folders to prevent access to your views by any means other than your controller.
