Process process = Process.Start(@"E:\test\test.ppsx");

I need to run the files in such a way that after finishing the first file ,second file should run automatically. can some one suggest me how can achieve that.

You can try using Process.WaitForExit() http://stackoverflow.com/questions/6390030/c-sharp-making-a-process-start-wait-until-the-process-has-start-up — Murkaeus, May 02 '13 at 07:35
Are you telling that after opening the first file you want to open another ? Not after closing the first file opening other — Guru Kara, May 02 '13 at 07:37

You can use WaitForExit method to wait to end process (Something like this):

var process1 = Process.Start(...);
process1.WaitForExit();

var process2 = Process.Start(...);

or subscribe into a Process.Exited event and execute another process after the first one. Check this for your reference.

You can use Process.WaitForExit method.

Instructs the Process component to wait indefinitely for the associated process to exit.

Also check Process.Exited event.

Occurs when a process exits.

Process process = Process.Start(@"E:\test\test.ppsx");
process.WaitForExit();

Use Process.WaitForExit()

class Program
{
    static void Main(string[] args)
    {
        Task.Run(() =>
        {
            Process.Start(@"c:\temp\presentation1.pptx").WaitForExit();
        }).ContinueWith(o => 
        {
            Process.Start(@"c:\temp\presentation2.pptx").WaitForExit();
        });
        Console.ReadKey();
    }       
}

You should get all the ppsx files from the test directory in the E drive in an array and process on the array of ppsx files according to your requirements.

 string[] files = Directory.GetFiles("your path");

loop through the array and pass each file path to the Process constructor and as lexeRoy said you can WaitForExit.
