Exception while uploading large file using backload file uploader

Question

I am using backload file uploader to upload files, its working fine with files with around 200-300 mb but for larger files 700-1000 mb, its failing and not even throwing proper (its going into handler_StoreFileRequestException but passing parameter as null) exception.

it first shows loading progress bar properly on page and keep loading and once it finish, during debugging its not hitting handler_StoreFileRequestStarted and directly hitting handler_StoreFileRequestException and in that their is parameter StoreFileRequestEventArgs which is comming null in this case.

to support big files i have made some changes in web config like:

<system.web>
       <httpRuntime executionTimeout="5000" maxRequestLength="1073741824"/>

and

<system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="1073741824"/>

but still facing issue..

Please suggest..

To upload large files in smaller chunks, set the maxChunkSize option to a preferred max size in bytes:

$('#fileupload').fileupload({
    maxChunkSize: 10000000 // 10 MB
});

For chunked uploads to work in firefox versions 4 thru 6 (xhr upload capable Firefox versions prior to Firefox 7), the multi-part option also has to be set to false (see the Options documentation on maxChunkSize for an explanation).
