C# How to Update a folder?

Question

I have a folder in program files called "Old" and "New".

I would like to copy files from "New" to "Old". The files and folders/subfolders in "New" Are the same as the ones in "Old" accept they are updated.

Is their an easy way to do this rather than myself having to check if each file exists and deleting it before moving the new files?

Program will be ran as administrator.

I have a lot of files i would like to delete/replace and typing each one out individually and having all this process on one button is taking me forever to write. Is their a way i can move all files folders and subfolders in New to Old and move and replace them all in one go?

This is for C# for Windows Forms App

You could use

Directory.Move(sourcename,destname;

for directories and for files

File.Move(sourcename, destname);

Hope this will solve your problem.

i thought that file.move only worked for a file?

i was looking at using File.Copy(sourcename, destname); But i dont think that will work? If their is an error in moving the file such as user permissions what would happen?

The files and subdirectories will already exist as i wold like to update them. I was hoping their is a way to move all of the files and subdirectories at once... And some files i would like to keep in the original folder which i will not be moving from the New folder.

C#

private static void CopyFilesRecursively(String SourcePath, String DestinationPath) 
{ 
   // First create all of the directories 
   foreach (string dirPath in Directory.GetDirectories(SourcePath, "*", SearchOption.AllDirectories))
      Directory.CreateDirectory(dirPath.Replace(SourcePath, DestinationPath)); 

   // Copy all the files 
   foreach (string newPath in Directory.GetFiles(SourcePath, "*.*", SearchOption.AllDirectories))
      File.Copy(newPath, newPath.Replace(SourcePath, DestinationPath)); }

This works but it says a file in the directory already exists... But i made it so if the folder exists it is deleted before i copy the new folder
