Filesystemwatcher - is this the best approach?

Hello guys,
i know some might complain this should be in the C# section but i wrote it in C++ and also there seems to be more support going on in the C++ section.

I have written some code to monitor multiple files in different directories, essentially i created a seperate thread for each directory and file specified. My question is is this the best approach if i want to monitor multiple files in seperate directories?

here i create the threads for all the files and directories specified

Code:

        Thread^ t;
        for(int i = 1; i <= (length-1)/2; i++)
		{
            // Supply the state information required by the task.  
            // Create a thread to execute the task, and then
            // start the thread.					
            t = gcnew Thread(gcnew ThreadStart(gcnew ThreadWithState(args[j],args[j+1]), &ThreadWithState::ThreadProc));
            t->Start();
			j+=2;
		}
		Thread::Sleep(0);
        Console::WriteLine("Main thread does some work, then waits.");
        t->Join();

and here is the function invoked:

Code:

    void ThreadProc()
   {
       ... ...
      ........

        watcher->NotifyFilter = static_cast<NotifyFilters>(NotifyFilters::LastAccess |
			NotifyFilters::LastWrite | NotifyFilters::FileName );
		watcher->Filter = getFileName(); 
		/*map the events to the corresponding handler / call back function*/
        watcher->Changed += gcnew FileSystemEventHandler( ThreadWithState::fileChanged );
		watcher->Deleted += gcnew FileSystemEventHandler( ThreadWithState::fileDeleted );
		watcher->Created += gcnew FileSystemEventHandler( ThreadWithState::fileCreated );
	    watcher->Renamed += gcnew RenamedEventHandler( ThreadWithState::fileRenamed );	
        watcher->EnableRaisingEvents = true;

		while ( Console::Read() != 'q' );
		watcher->EnableRaisingEvents = false;

   }

essentially it is creating a Filesystemwatcher per file monitored in the directory.
If i wanted to monitor hundreds of files all in seperate directoreis will this be efficient enough?

Why do you keep starting new threads on the same subject?

Because each one is in a different directory, lol.

ok ok i understand the joke. The thread is similar but not the same question as the previous thread. Do you think this is the best approach to go by with what i want?

Why do you think something that is not C++ should go into the C++ section?
Let me repeat: THIS IS NOT C++.
Thus, C++ programmers CANNOT HELP YOU.
Stop posting threads all with the same subject and leave them in the tech board or C# section. if someone with actual knowledge of the language you're using comes along, you can be certain they'll check THAT section of the board, as well.

Are you sure? It looks like C++ to me....

Google the gcnew keyword. It's not C++.

Only you can define 'efficient enough'. Therefore, why don't you try it and tell us if it's efficient enough?

Basically, you have two options: create a FileSystemWatcher per Filter, or create a FileSystemWatcher that watches C: and ignore events generated by files that you don't care about. After a cursory glance at a Google search (you did do that before asking this question twice on the forums, right?), most people suggested the first way.
