C＃将文件重命名为与其他目录中的文件相同的名称

Question

For example I have 2 directories with both the same file, and when I renamed the file in the 1st directory, it should be renamed in the 2nd directory as well. If the file is renamed in the 2nd directory, I dont want it to be renamed in the first. So just one way. Now people use File.Move for renaming in the same directory, but that wont work for me, since I dont want the file to be gone from the first directory. So I figured I should use Copy , but the problem is, if it copies the 2nd directory has 2 files. 1 with the old name (since it already existed) + the copy of the file in the first directory. So I figured I have to delete the old file in the second directory, but for some reason this wont work for me. It wont delete the old file.

Here is my code:

private void fileSystemWatcher1_Renamed(object sender, RenamedEventArgs e)
{
    String source = ConfigurationManager.AppSettings[@"Directory1"]; // defined this in the app config
    String target = ConfigurationManager.AppSettings[@"Directory2"];
    filepath = Path.Combine(source, e.Name);
    veryoldname = Path.GetFileName(filepath);

    File.Delete(Path.Combine(target, veryoldname));
    File.Copy(filepath, Path.Combine(target, e.Name)); 
}

I was wondering 3 things here.

1. Is this the best way to rename a file according to a file in a different directory?
2. If not, how should I do it?
3. What am I doing wrong here?

Here's the comment discussion rolled into an answer:

Change:

veryoldname = Path.GetFileName(filepath);

To:

veryoldname = e.OldName;

And change:

File.Delete(Path.Combine(target, veryoldname));
File.Copy(filepath, Path.Combine(target, e.Name)); 

To:

File.Move(Path.Combine(target,veryoldname),Path.Combine(target,e.Name));
