The RequireRootedSaveAsPath property of the HttpRuntimeSection object is set to true, but filename is not an absolute path.

The maximum size allowed for a request, which includes uploaded files, is 4 MB, by default. Maximum request size can be specified in the Machine.config or Web.config file in the maxRequestLength attribute of the httpRuntime Element (ASP.NET Settings Schema) element. The maximum request size for a specific page can be specified using the location Element (ASP.NET Settings Schema) element in a Web.config file.

The following code example demonstrates how to save all the files that are uploaded by the client to the C:\TempFiles folder on the Web server's local disk.

String TempFileName;
 HttpFileCollection MyFileCollection = Request.Files;

 for (int Loop1 = 0; Loop1 < MyFileCollection.Count; Loop1++)
 {
    // Create a new file name.
    TempFileName = "C:\\TempFiles\\File_" + Loop1.ToString();
    // Save the file.
    MyFileCollection[Loop1].SaveAs(TempFileName);
 }
