How to get the file move process name/id : I want to move several files that names are saved in an `ObservableCollection<String> _collection` with this method:
    
    string firstFolderThatContainsEveryFile = "...\Folder\Files";
    string secondFolderArchiv = "...\Folder\Files\Archiv";
    foreach (var item in _collection)
    {
         string firstFolder = System.IO.Path.Combine(firstFolderThatContainsEveryFile, item);
         string secondFolder = System.IO.Path.Combine(secondFolderArchiv, item);
         File.Move(firstFolder, secondFolder);
    }

This works at the first time, but if i load new files into `firstFolderThatContainsEveryFile` and try to use my move method i get an exception:

> process is already in use

**How can i get the processname or processID to close the process before i use my move method, or is there even a better way to get around this?**
