Hi Srinath There is a way that you can store that all files into an array or arraylist or list of string and then can easily iterate over them. You have use session and there is only change of one digit from these 5 sessions so you can write something like this, string a = "a"; string b = "b"; string c = "c"; string d = "d"; string f = "f"; Session["str1"] = a; Session["str2"] = b; Session["str3"] = c; Session["str4"] = d; Session["str5"] = f; ArrayList arr = new ArrayList(); for (int i = 1; i { arr.Add(Session["str" + i + ""].ToString()); } for (int j = 0; j { //Here you can use your fileuploads for further process. } Hope it helps you. Thanks.
