Have you tried FileSystemWatcher class? Its easy to implement and it triggers when there is a modified/delete/new file was done. https://www.c-sharpcorner.com/UploadFile/puranindia/filesystemwatcher-in-C-Sharp/

Maybe thats why you don't know what is in your " filenamesource" and "filenamedest "? Method "GetFiles" returns full path with file name. You can display result in your console and then try do something.

string source = @"e:\source\"; string dest = @"e:\dest\"; string[] filesorce = Directory.GetFiles(source); string[] filedest = Directory.GetFiles(dest); foreach (string filenamesource in filesorce) { foreach (string filenamedest in filedest ) { if (filenamesource == filenamedest) { } else { File.Copy(source, dest, true); } } } i tray this but its not working

Algorithm: 1. List files. https://docs.microsoft.com/pl-pl/dotnet/api/system.io.directory.getfiles?view=netcore-3.1 2. Compare files by name maybe? Or other properties you can use e.g. class FileInfo. https://docs.microsoft.com/pl-pl/dotnet/api/system.io.fileinfo?view=netcore-3.1 3. Copy files if not exists in target path.
