I let users upload files using the asp.net upload control. I have a repeater on a page that list the files and users can click to download them:

```
    protected void grdFiles_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType != DataControlRowType.DataRow) return;

        var fileNameFull = Common.FileHelper.UploadPath + e.Row.Cells[0].Text;

        Request.MapPath(fileNameFull);

        var hyp = new HyperLink
                      {
                          NavigateUrl = fileNameFull,
                          Text = e.Row.Cells[0].Text,
                      };
        e.Row.Cells[0].Controls.Add(hyp);
    }

```

this works fine when the files are on the same drive as the web application, fileNameFull looks like: `~\Uploads\some pdf.pdf`

The requirement now is that files are going to be stored on a different drive so my question is how can I achieve this? Request.MapPath obviously expects a virtual path. 

The files needs to be exposed to users over the web, security is not the main concern.

Thanks in advance.
