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.

Hi,
Refer to this link for a detailed Multiple file upload with ASP.Net
But the code is in vb.net, if you want the code in c# then just use any code converters.
here is the link

How to control the size of file uploaded to the web server?
While uploading a file to the web server, we have a limit of 4MB by default. We can either decrease or increase this value. The value is set in the key, maxRequestLength of machine config file.
There is a maxRequestLength limit in the machine.config file (look for the <system.web> section), in the httpRuntime settings that you need to alter/raise if you want to accept anything larger than 4Mb. These are the standard settings for the httpRuntime:
U can use this link!!
http://aspalliance.com/150_how_to_upload_files_in_asp_net
<httpRuntime executionTimeout="90" maxRequestLength="4096"
useFullyQualifiedRedirectUrl="false" minFreeThreads="8"
minLocalRequestFreeThreads="4" appRequestQueueLimit="100"/>
