moving duplicated directories back to root directory

I accidentally ended up with a bunc开发者_如何转开发h of my directories getting borked, what should be:

/myroot/mydirectory

ended up as:

/myroot/mydirecotry/mydirectory/mydirectory

Then nesting could be any where from 1 to N times - I need to find the furthest out /mydirectory and copy all of those files back to the root and kill the duped ones. How do I find the one that is furthest out?

string[] dirs;
string actualDir = @"\myroot\";
string subdir = "mydirectory";

do
{
    dirs = System.IO.Directory.GetDirectories(actualDir, subdir);
    actualDir += subdir + @"\";
}
while (dirs.Length > 0);

string theLongestPath = actualDir; // The path to the furthest dir

This gets all directories in actualDir that contains subdir, until it's the last one (no other subdirectories containing subdir). If you have any questions on how it works, ask in a comment. And yeah, I've tried it, it really works.
