Make a downloadable Hperlink field in Gridview using Physical path

I want to set a download link in my gridview , the thing is that I have set a physical path while Uploading the file and saving the file name and its pyshical path in the database

if (fileUpTimeTable.HasFile)
{
    string TimeTableFileName = fileUpTimeTable.FileName;
    string TimeTableFilepath = "D:\\My_Drive\\Kunal_backup\\Kunal\\StudentDesk_aarti\\StudentDeskv2\\Download\\TimeTable\\";
fileUpTimeTable.SaveAs(TimeTableFilepath+fileUpTimeTable.FileName);
FillGrid();
}

The Uploading works fine and the file and its filepath gets saved in the database successfully.
The gridview also shows the correct data but I am not able to download the uploaded file from the gridview

Following are Database fields
ID --Pkey
FILENAME -- e.g abc.pdf
FILEPATH --

D:\My_Drive\Kunal_backup\Kunal\StudentDesk_aarti\StudentDeskv2\Download\TimeTable\abc.pdf

Please guide me how can I accomplish the same

<asp:HyperLinkField DataNavigateUrlFields="FILENAME" DataNavigateUrlFormatString="{0}"
                            Text="&lt;img src='../IMAGES/download.jpg' style='border:none'&gt;" HeaderText="Download" Target="_blank"/>

P.S : I am not using Virtual path , but Physical because I need to share these uploaded file between two different Project Solutions
