Hi, >From my (bad) memroy, ThreadPool is implemented. There is only a small difference between default number of thread pool.
By using ThreadPool, you can't have a direct pointer on the launched Thread, so you will have to deal with other concurency management (Semaphore, mutex, or other waithandle) to wait for all task to be completed. I may be wrong, but reading lots of files at the same time, can the hard drive support the required bandwith ?
