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.
