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.

String tempFileName;
HttpFileCollection myFileCollection = get_Request().get_Files();

for (int loop1 = 0; loop1 < myFileCollection.get_Count(); loop1++) {
    // Create a new file name.
    tempFileName = "C:\\TempFiles\\File_" + String.valueOf(loop1);
    // Save the file.

var tempFileName : String
var myFileCollection : HttpFileCollection = Request.Files

for(var i=0; i < myFileCollection.Count; i++){
  // Create a new file name.
  tempFileName = "C:\TempFiles\File_" + i
  // Save the file.
