MVC : Upload List of files and save in Folder(name-GUID) for individual

Question

I want to upload multiple files from the various user and saves them all at server with individual folder for each user,which contains list of uploaded files by him.

Requirement:If user uploads 5 files,all five files will be stored within a single folder with GUID FolderName.

My below code creates a new folder for each files upload by a user. Ex:If user uploads 5 files,all five files will be stored within five different folder with GUID FolderName.

My Controller Upload method is as shown below:

 ##Controller Code##

    public string Upload(HttpPostedFileBase fileData)
    {            var testfolder = this.Server.MapPath("~/uploads/");
             string newGuid = Guid.NewGuid().ToString();
             string pathToCreate = Path.Combine(testfolder, newGuid);
             if (!System.IO.Directory.Exists(pathToCreate))
             {
                 System.IO.Directory.CreateDirectory(System.IO.Path.Combine(testfolder, newGuid));
             }
             var fileName = pathToCreate + "//" + System.IO.Path.GetFileName(file.FileName);
             file.SaveAs(fileName);                              
             return "OK"; 
     }

##View Code##

  @{
  Layout = "~/Views/Shared/_Layout.cshtml";
  }
   <link href="@Href("~/Content/uploadify.css")" rel="stylesheet" />
 <link href="@Href("~/Content/bootstrap.css")" rel="stylesheet" type="text/css" />
 <div class="row">
 <div style="width: 50%;">

        <input type="file" id="multipleFiles" style="width: 50%;" /><div style="width:     77%;
            float: right" id="progressbar">
        </div>
    </div>
    <div id="fileQueue"></div>
   </div>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"                          type="text/javascript"></script>
     <script src="@Href("~/Scripts/jquery-1.9.1.js")" type="text/javascript"></script>
      <script src="@Href("~/Scripts/bootstrap.js")" type="text/javascript"></script>

        <script src="@Href("~/Scripts/jquery.uploadify.js")" type="text/javascript">   </script>
        <script type="text/javascript">

         $(function () {
     $("#multipleFiles").uploadify({
        'swf': 'Scripts/uploadify.swf',
        'cancelImg': '/Images/trash.jpg',
        'buttonText': 'Add Documents',
        'uploader': 'Upload/Upload',
        'folder': '/uploads',
        'dataType': 'json',
        'fileDesc': 'Image Files',
        'fileExt': '', //'*.jpg;*.jpeg;*.gif;*.png',
        'multi': true,
        'removeCompleted': false,
        'auto': false,
        'height': '30px',
        'queueID': 'fileQueue'
           });
   });
</script>

Ok, given that you can't use Sessions, I propose the following:

Generate the GUID in the view and include the url as part of the url you are posting to:

Warning: this code comes with no guarantee, I have not tested it so may need some adjustment. Please consider the idea behind it to be more important. :)

View Code:

 $(function () {

     var guid= '@(Guid.NewGuid().ToString())'; //generated on render time

     $("#multipleFiles").uploadify({
        'swf': 'Scripts/uploadify.swf',
        'cancelImg': '/Images/trash.jpg',
        'buttonText': 'Add Documents',
        'uploader': 'Upload/Upload?guid='+guid, //modified to include guid
        'folder': '/uploads',
        'dataType': 'json',
        'fileDesc': 'Image Files',
        'fileExt': '', //'*.jpg;*.jpeg;*.gif;*.png',
        'multi': true,
        'removeCompleted': false,
        'auto': false,
        'height': '30px',
        'queueID': 'fileQueue'
     });
});

Controller Code:

public string Upload(HttpPostedFileBase fileData, Guid guid)  {
    //now you can use the guid to save the files
}
