Hi, For checking new files in directory WinAPI functions can be used. Waiting for notification will be in any case better than polling.
See some info on msdn site: Obtaining Directory Change Notifications http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/base/obtaining_directory_change_notifications.asp ReadDirectoryChangesW http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/base/readdirectorychangesw.asp FindFirstChangeNotification http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/base/findfirstchangenotification.asp
