Hello friends..,

Greetings!!!!!
 I have an application(client) from which i upload files to the server. I did that upload part. But now i have a problem with that. In my application different users login and upload their files. For each user their will be seperate login.

The problem is that i need to create a folder in the server spontaneously when a particular user tries to upload a file and also i need to rename that file when it is saved in that folder so that if the user tries to upload a file again with the same name it should not be overwritted.I am giving the code that i used to upload below:


protected void Button1_ServerClick(object sender, EventArgs e)
    {
        //Uploading the attached file
if ((File1.PostedFile != null) && (File1.PostedFile.ContentLength > 0))
        {
            string fn = System.IO.Path.GetFileName(File1.PostedFile.FileNa me);
            string SaveLocation = Server.MapPath("Data") + "\\" + fn;
            try
            {

                File1.PostedFile.SaveAs(SaveLocation);
                Response.Write("file Uploaded");

            }
            catch (Exception ex)
            {
               Response.Write("Error:" + ex.message);
    //Note: Exception.Message returns a detailed message that describes the current exception.

            }
        }
        else
        {


        Response.Write("Please select a file to upload.");

        }


    }



so guys please help me for the above problem as early as possible.


Thanks & Regards,

Pramod.
