    This is a bit too open ended question. Which part of this are you having trouble? – Sami Kuhmonen May 31 '22 at 07:22
  • i created 2 array for store file names from the directory.. – Joseph May 31 '22 at 07:25
  • "i created 2 array for store file names from the directory" ok please post this code. How do you compare the content of the suspicious file? – Mong Zhu May 31 '22 at 08:01
  • Are you sure you can't use [robocopy](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/robocopy) for this? `robocopy /xc /xn /xo /mov source destination ` – Matthew Watson May 31 '22 at 08:19

Something like this?



        private void CopyMissedFiles(string source, string destination)
        {
            var sourceDir = new DirectoryInfo(source);
            var destinationDir = new DirectoryInfo(destination);
            var sourceFiles = sourceDir.GetFiles();
            var destinationFiles = destinationDir.GetFiles();
            foreach (var file in sourceFiles.Where(x => destinationFiles.All(y => y.Name != x.Name)))
            {
                file.CopyTo(Path.Combine(destinationDir.FullName, file.Name));
            }
        }

Update: if you need to compare the file content, you can use MD5 hash to do that. Here is the description, how to calculate the hash Calculate MD5 checksum for a file
