] | You will need your own implementation of `ToString` in your `Employee` class. You just need to override it and put your code of `PrintEmployee` in the new method.
Just to make it clear what I mean I give you a sample on how the override should look like:

public override string ToString()

] | The `u` just indicates that it is a unicode string and is not relevant to the problem.
The file isn't found because you aren't adding the `mypath` in front of the filename - try `with open(join(mypath, myfile)) as f:` | Your problem is that `myfile` is just a filename, not the result of `join(mypath,myfile)`. |

] | Your code does not work because it uses [`os.execvp`](https://docs.python.org/3/library/os.html#os.execvp). `os.execvp` **replaces the current process image completely with the executing program**, your running process **becomes** the `ls`.

Call this before you call os.execvp() and it will create a child process. os.fork() returns the process id.
