Uploading Large Files in sharepoint 2013/2010/2007

Change the maximum upload size on the web application level

Central Admin>Application Management>Manage Web Applications> Select the desired web app and click General Settings on the ribbon

Modify the web.config file for the appropriate web application, this is located by default at C:\inetpub\wwwroot\wss\VirtualDirectories\web application name or port

• Make a backup copy of the web.config, then open it
• Do a Ctrl+f to find this element 

<httpRuntime maxRequestLength="51200" requestValidationMode="2.0" />











Modify the above element to match the following

<httpRuntime executionTimeout="999999" maxRequestLength="2048000" requestValidationMode="2.0" />

In the above step we added executionTimeout="999999" and we set the maxRequestLength to what we set the maximum upload size on the web application general settings, which is 2048000 (2000mb * 1024 = 2048000)
