Hi Devi,
You can use the Html control or Asp control to browse the file from spacific directory.
add a input button from the toolbox of Html control. and set the type is "File" of that control.
now you'll see that a browser button will be displayed. now you can select the files through this browser button.
To save the file, you can use this code:
bttBrowse.SaveAs("c:/tt.txt");
where bttBrowse is the name of control which is added.
I think this will be help to you. If want to more information then you can tell or ask to me.
ok byeee...

Dear Devi,
If you want to fetch all the files from the specific directory, then you cannot use the file upload control. You have to give the folder path manually,
After that you can use the System.IO namespace and get all the files in the given directory and move to the server.
other wise, View this link given below. I hope, it will help you to move further.

All the Best :)
