First of all, as UI involved, you need to tag it: WPF? Forms? Silverlight? ASP.NET? what?..

Oh, I see: Winforms. Then tag it: "Forms".
For Windows applications, the problem is pretty simple, just use System.IO. So, what's the problem? What have you done so far?

I've done this in a windows form application but still unable to control the progress bar according to the file size ,and copied files

There is no a hook into that (when a file is only partially copied), so you need to copy a file on a low level, block by block (of some size), smaller files should go by all 100% at once. I wonder why?

You start at the root folder of your copy job, getting the file information for every file in that folder, adding up all the file sizes, and recursively traversing the entire subfolder structure under the root, continuing to inventory all the file for size information.

Then, you go back to the root folder and start copying files, one by one, creating all the folders in the root on the target. Again, you recursively do this same thing in each and every folder in your source folder.

Keep track of the number of bytes you've copied and you can easily get the percentage complete for your progress bar.

Oh! You'll want to put the file inventory and copy code in a seperate thread so you can keep the UI thread available to handle screen updates and user clicks, like the Cancel button.
