title: FileSystemWatcher does not work properly when many files are added to the directory at the same time
body: <p>FileSystemWatcher does not work properly when many files are added to the directory at the same time...</p>
  
  <p>The Watcher simply doesn't find all the files in the directory - only if the files are placed in the folder one by one - not if lots of files are copied to the folder at the same time...</p>
  
  <p>Is the creation of Threads the solution to the problem or is there another way to handle the problem ?</p>
