Access local machine folder items

Question

I am rewriting an VB6 desktop application into Web application, since its a desktop application its using the users local machine folder to view word documents. I want to implement the same in the web application. I don't want to use the server documents, instead I want to use the users local machine to access those documents.

 

  protected void Page_Load(object sender, EventArgs e)
    {
        BasDebugMessages debug = new BasDebugMessages();
        string strWordTemplatePath = "";
        string strInitialFile = "";
        try
        {
            string strWordTemplate = Request.QueryString["file"].ToString();
            string PersonType = Request.QueryString["PersonTypeCode"].ToString();
            ViewState["PersonTypeCode"] = PersonType;
            if (PersonType == "A")
            {
                strWordTemplatePath = "C:\\Program Files\\Microsoft Office\\Templates\\APS Reports\\";
                strInitialFile = strWordTemplatePath + "B2590.ini";
            }
            else
            {
                strWordTemplatePath = "C:\\Program Files\\Microsoft Office\\Templates\\JAS Reports\\";
                strInitialFile = strWordTemplatePath + "A2580.ini";
            }

            string strWordTemplateDot = Path.GetFullPath(strWordTemplatePath + strWordTemplate + ".dot");
           
            if (!File.Exists(strInitialFile))
            {
                StreamWriter sw = File.CreateText(strInitialFile);
            }

            System.IO.FileInfo file = new System.IO.FileInfo(strWordTemplateDot);
            if (file.Exists)
            {
                string path = file.DirectoryName + "\\" + strWordTemplate + ".dot";
                FileStream outputfile = new FileStream(path, System.IO.FileMode.Open);
                byte[] fileData = new byte[outputfile.Length];
                outputfile.Read(fileData, 0, Convert.ToInt32(outputfile.Length));
                outputfile.Close();

                EditIniFile(strInitialFile, strWordTemplate);
                HttpContext.Current.Response.ClearContent();
                HttpContext.Current.Response.ClearHeaders();
                HttpContext.Current.Response.Buffer = true;
                HttpContext.Current.Response.Expires = 0;

                HttpContext.Current.Response.ContentType = "application/msword";
                HttpContext.Current.Response.AppendHeader("content-disposition", "attachment; filename= " + file.Name);
                HttpContext.Current.Response.BinaryWrite(fileData);
                HttpContext.Current.Response.Flush();
                HttpContext.Current.Response.End();
                HttpContext.Current.ApplicationInstance.CompleteRequest();
            }
        }
        catch (ThreadAbortException)
        {
        }
        catch (Exception ex)
        {
            debug.Insert(ex.Message);
        }
    }
