Effective copying multiple files

Question

I have to copy quite a lot of files from one folder to another. Currently I am doing it in this way:

string[] files = Directory.GetFiles(rootFolder, "*.xml");
foreach (string file in files)
{
    string otherFile = Path.Combine(otherFolder, Path.GetFileName(file));
    File.Copy(file, otherFile);
}

Is that the most efficient way? Seems to take ages.

EDIT: I am really asking if there is a faster way to do a batch copy, instead of copying individual files, but I guess the answer is no.

Answer 1

I can't think of a more efficient way than File.Copy, it goes directly to the OS.

On the other hand if it takes that long, I would strongly suggest to show a progress dialog - like SHFileOperation does it for you. At least your users will know what is happening.
