Answer 1

This setting configures the upload file size limit:

<system.webServer>
    <security>
            <requestFiltering>
                <requestLimits maxAllowedContentLength="10485760"/>
            </requestFiltering>
  </security>
</system.webServer>

Default size is ~30Mb.

Set your web.config with the following where xxx is the max upload size in kilobytes:

<configuration>
  <system.web>
    <httpRuntime maxRequestLength="xxx" />

</configuration>

The default is 4096 (= 4 MB). MSDN documentation
