Hi,

I have folder which is deep rooted (i.e many folders and files under it)
My requirement is to execute a command on each file on the above folder recursively and it should be fast.

My approach was to use to the Directory Get Files method to get the files in an array and loop though each file . While Looping through , I use the Process class something like this

Process P =new Process();
p.StartInfo.command="someexe";
p.StartInfo.arguments="<dynamically set by the filevalue in the loop everytime>";
p.Start();
p.WaitForExit();

The above method of execution takes an hour or so. Can I make the process faster using threads if so how ?

This sounds too much like something to do with spyware, viruses, or other generally annoying things. Can you explain what you are doing first?

Hehe..
It is for labelling the source control (i.e Clearcase view that has the files loaded in it ). So trying to automate the same with a C# script which will call "cleartool.exe with a parameter of the path of the file to do the job. Hence the requirement to loop over all the files.

Well for starters the p.WaitForExit() does just that... do you need to wait for the process to exit or are you just trying to stop 9999 processes from spawning at once? If so you could do something to only have N processes started by the application at once.

Threading is a possible solution but there is also overhead in creating and tearing down a thread, so you need to give us a little more information on this.

Let us not spawn 9999 processes of the cleartool.exe at once . That will make it really fast, bur atleast create a thread or two to the job run faster than the current one .

Best answer would be to recursively get a list of files, and pop the filename in a list

Then have a class which spawns say 5 threads max, and processes the file, so you dont thrash the heck out of everything but also achieve a realistic effect

ignore - dup

Anybody ?

ppraj, your last post has no point. You were the last to answer before me, I said something your response is clearly not in relation to that, so what was the point?

Yeah, I didn not see that..thanks
I'm aready loopinh though the files list, so the point it to spawn the prcoess across 5 threads. How can I do that ?
I also have a query like , when you spawn the process, how are you going to keep track of the files that are already prcessed by some other thread. To that I mean , we should not process a file in the list if the other thread has taken care of it.
