You have not done anything wrong. When you are working with CodeWarrior or Matlab using the applicatoin server, the Desktop it shows is the dektop on your Z: drive and not your local computer's. So when you saved the files, you had actually saved it on the server. This is why you can't find it on your computer's Desktop. To save a file on your computer, you'll have to choose the V: drive or the U: drive. The C: drive on your computer is mapped as V: drive and the D: drive on your computer is mapped as U: drive. So, save the files in V: drive and then you should be able to find it in your C: drive.
