title: windows bat's multithreading and execution of other application
body: <p>New issue came up for me recently. I often must run simillar tasks and I would like to make my life easier. </p>
  
  <p>Basicaly after choosing argument i always run one exe file with this argument and after that (these should work in the same time) I run bat file (with argument too).</p>
  
  <p>After finishing I make some copies of generated files and move them to particular directories (all i based on argument sent while executing). Then all operations are reapeted many times.</p>
  
  <p>Doing it manually is waist of time in my opinion.</p>
  
  <p>Could you recommend any approach that would handle multithreading while working with files and  directories?</p>
