string filePath;
filePath = Server.MapPath("/BMMIC/Downloads/");
//Here Give the path of the folder. BMMIC is Project Name and Downloads Is a Folder inside it.


DirectoryInfo dirInfo = new DirectoryInfo(filePath);
FileInfo[] info = dirInfo.GetFiles();
DirectoryInfo[] dirs = dirInfo.GetDirectories();


DataTable dt = new DataTable();
dt.Columns.Add("Filename", typeof(string));
dt.Columns.Add("Size (kb)", typeof(int));
//dt.Columns.Add("Type", typeof(string));
dt.Columns.Add("Modified", typeof(string));


DataRow dr;
foreach (DirectoryInfo dir in dirs)
{
dr = dt.NewRow();
dr["Filename"] = dir.Name;
dr["Size (kb)"] = "0";
//dr["Type"] = "Directory";
//dt.Rows.Add(dr);
}
foreach (FileInfo file in info)
{
if (file.Name.EndsWith(".htm") || file.Name.EndsWith(".html") || file.Name.EndsWith(".txt") || file.Name.EndsWith(".pdf") || file.Name.EndsWith(".xls"))
{


dr = dt.NewRow();
dr["Filename"] = file.Name;
dr["Size (kb)"] = (int)file.Length / 1024;
//dr["Type"] = "File";
dr["Modified"] = DateTime.Parse(file.LastWriteTime.ToString()).ToString("MM/dd/yyyy h:mm tt");
dt.Rows.Add(dr);
