Parallel Robocopy

Question

Hi All Am trying to copy files from a single source to multiple destinations. I dont want this copy to happen sequentially. I want the files to be copied at the same time to all destinations in parallel. How is it possible to do with robocopy as a command line argument? Ex - Robocopy soucreDir ---destination1 -destination2 -destiantion3 in a single line command line argument. Or how can we do this in c#? Abraham

Hi It's very simple using System; using System.Threading.Tasks; namespace ConsoleApplication37 { class Program { static void Main( string [] args) { Parallel.ForEach(args (parameter) => { /// Async Execute. CopyFile(parameter); }); Console.WriteLine( Finish !!! ); Console.Read(); } public static void CopyFile( string destinator) { System.Threading.Thread.Sleep(1000); /// Your code Console.WriteLine($ Copy data to {destinator} ); } } }

I don't think you can have multiple destinations in a single invocation. However what you can do is have multiple command windows open with single source but different destination. This is even more simpler to do in C#. Write a function which would create a new process info object (google execute a program from c# code). Call this function with different destination parameter and it will automatically start different execution threads.
